Bicubic trabalhos

Hi all, In my project I'm creating my own dynamic library for interpolation of digital images in C language. I need a programmer who will implement two interpolation algorithms into my .c file: Total Variation and Gauss algorithm and fix the bicubic function (I wrote it but it doesn't work properly). I have the Total Variation and Gauss algorithms written in matlab. You will need to translate it into C and implement. The image input and output is done using the io_png.h library. Interpolated images are black&white (not necessary to write it for 3 channels). I have created a core of the library, I have created Makefiles also in the project. Candidate must have good knowledge of C programming. I can send you my project in DM.

...specifically look at the use of adversarial loss, which motivates the generator to create photorealistic images, and perceptual loss, which employs a pre-trained deep network to measure the similarity between the generated and ground truth images in terms of perceptual features. To determine the advantages and disadvantages of each approach, I will also contrast model-based approaches (such as bicubic interpolation) with model-free approaches (such as deep learning). The proposed solution is to create a new deep learning model for super-resolution that is capable of recovering fine texture details when upscaling by large factors. In a supervised setting, the model will be trained with multiple loss functions, including mean squared error (MSE) loss, perceptual loss, and a...

...In this work, we would develop an algorithm which can reduce the time of MRI and thus the cost, with minimal compromise on accuracy. Then we would reconstruct a three-dimensional (3D) image of the spine from a sequence of 2D MRI slices along any one axis with reasonable slice gap. In order to preserve the image at the edges properly, then regenerate the 3D image by using a combination of bicubic and bilinear interpolation along the orthogonal axis. From the reconstructed 3D image, then we would use a simple geometric method to slice out any possible location along any axis and get the information in that region. We would then test the algorithm on real data, and find the amount of time by which we can reduce the process of MRI process using the algorithm, with high inter...

There is MNIST database of 70000 28x28 grayscale pictures of 0-9 handwritten digits: You need to prepare two smaller resolution version of this dataset: 1. 10x10 version 2. 15x15 version You need to use good scaling algorithm like bicubic or similar quality. The result should be provided as ZIP archive in the following format of subfolders: * 10x10 * training images * PNG * CSV * testing images * PNG * CSV * 15x15 * training images * PNG * CSV * testing images * PNG * CSV Each PNG subfolder should contain thousands of PNG images names like , , etc. Each CSV subfolder should contain one file calledd "" in the same format like here:

I need a photoshop expert that can automatically upscale a set of 5,728 images to a larger image size. i.e. an Image like this; should be upscaled 500%, by using the best resampling method possible in Photoshop ( perhaps Preserve Details 2.0, but certainly not bicubic) Photoshop actions will be required, since there are too many to do manually. Input images will be Jpeg or PNG, in a vareity of sizes, output images need to be in either Jpeg or PNG format.

I wanted Bicubic interpolation function in c++ with simple parameters. look at attachment for calling example.

...spatial distortions, and image decompression, as well as others. Of the many image interpolation techniques available, nearest neighbour, bilinear and cubic convolution are the most common. [1] There are a number of techniques that can be used to enlarge an image. In this assignment, you are expected to implement three Interpolation methods (such as Lagrangian Interpolation, Cubic spline, bilinear, bicubic etc.) for three different images and compare the results. Step 1: Read Image I = imread(''); figure;imshow(I);title('Original Image'); Step 2: Simulate three Interpolation Methods For example , increase the dimensions of the image from 720x480 (typical resolution in DVD frames) to 1920x1080 (typical resolution in high definition HD video frames) 1.

...images that I need resized from the current size down to smaller sizes, but I need them to be kept as sharp as possible. I am unable to gain access to high resolution tiffs, so I am working from 1000x1000 72dpi JPG or PNG files. These are product images and the labels when resized get blurry. There are also two banners that need to be resized. A total of about 10 images. If you're going to do a bicubic sharper or a basic unsharp mask, don't bother bidding. I can do the basic photoshop stuff. Don't bother bidding near the upper end of this range if you want to bid on this. Not a lot of back and forth on this.

I got the attached script on my osCommerce website. All it does is taking images and re-sizing them, while applying watermark and caching them to browser and my server. The short script is using the GD library, and since the output of a downsized image is not sharp enough (kind of looks like it is using something similar to bicubic smoother algorithm) I would like to convert it to use ImageMagick instead as it can downsize while using "Bicubic Sharper" method and maintain the sharpness of a reduced-size image. I want to keep the script as close as possible to its original form and certainly to keep all the watermarking & caching and other functionality it currently has. This should be a very simple job for a professional who's experienced with such work,...

...few notes of interest: - You cannot count on the source images (either the ones in 600dpi-Photoshopped or the ones in Web-Lossless) being .psd or .png or .jpg. I assume ImageMagick will just take whatever you throw at it, though! - When I say fit width, I mean that it should be resized proportionally down to fit inside the bounds of 1600px width and unlimited height. Of course, it should be bicubic, or whatever, the highest possible quality. - When I say an adaptive palette, I just mean whatever looks best. I'm used to using Fireworks and Photoshop to manually (or batch) export these images, and, for example, Fireworks' "Adaptive" colour palette choice always turns out great. I definitely DON'T want to be limited to a predefined 16 or 256 color pale...

...on Gdiplus (b) Is faster than the Gdiplus version. Please see the attached zip for exact spec. The .zip contains the current Gdiplus-based function and screenshots on XP (with default theme active) of it's result. What I need you to do is replicate the functionality exactly. Note this will involve both bilinear and bicubic filtering algorithms. You can, however, assume that the bilinear algorithm will only ever be used to scale up, while the bicubic will only ever be used to scale down. (See code in attached .zip) The most important requirements here are: 1. That your implementation is deterministic in producing exactly the same result as the existing function (within reason). Specifically, on XP with default theme active, if you use (fo...

...image then resized with a width of 680 pixels, keeping the height in proportion (Photoshop: Constrain Proportions). For a lot of these images the size will then be 680 x 510. However: For some of the images the width is already below 680 pixels. If this is the case then you must enlarge the image to make the width 680px using the following Photoshop option: Image Size > Resample Image (Bicubic Smoother/Best For Enlargement) 2. You then need to rename each image in the following way. For the first image, Elmo Cake, you would name it "" For the second cakes, Sesame Street Cupcakes, you would name the image "" if there is a Happy Birthday on the cake then you insert the 'birthday-cake" into the file name

Gday, Working on a picture editing software which I got as project at my work to improve productivity... my last task is to code a function with which you can scale a picture stepless. Meaning in our GUI is a slider with which you can select a picture size (in %, smaller or bigger) and then it adjusts to that size. As algorithms I can use either nearest neighbour, bilinear or bicubic. I found already some good stuff on that site: So what do I need? A simple class to which I can pass an image (format bmp) which then is rescaled by using one of the algorithms mentioned above. To avoid misunderstandings: We are NOT allowed to use the java internal functions, the algorithm has to be coded by hand (so no use of “scale normal??

We need to implement fast bicubic (2D) image interpolation, to support image resizing. It should provide interpolation quality, visibly superior to linear interpolation, and be implemented as the following function: void Interpolate( unsigned char* pScrBuffer, // source image buffer int SrcBpp, // bytes per pixel in the source image int SrcW, int SrcH, // width and height of the source image unsigned char* pDesBuffer, // destination (interpolated) image buffer int DesW, int DesH, // width and height of the destination image int SrcX0=0, int SrcY0=0, int SrcX1=1000000, int SrcY1=1000000) The main goal of this project is the interpolation SPEED. In fact, we do have already Interpolate() function implemented with standard C code and all simple “soft?? optimizatio...

We are looking for a working solution to get around this problem asap. Please do not bid unless you know you can get working (small MFC C++ demo to show it working as a .exe will be advantageous), we can supply other masks if required. Masks can be shrunk as small as 10x10 and therefore you must test at various sizes. We have included the our PNG mask and also

...allows user to select an image on their hard drive of any size, resize it on the client, and then upload it to our web server. The flash program will do the following: 1. Allow the user to browse their hard drive for the image they want to upload. 2. Resize the image (before upload). Since flash can not do this natively, you will need to import the image, convert to bitmap, and implement a bicubic resizing algorithm to resize the image. As a result resizing should be smooth and maintain image quality. 3. If possible convert the resized image into a jpeg. Since this can not be done natively you will need to implement the jpeg compression algorithm. 4.

Java class to resize, rotate, and invert (negative image) a very large 8 bit grayscale TIFF file and save in RAW format. Conversion must use bicubic interpolation. Input is source TIFF file path, final horizontal and vertical pixels (resize is not orthogonal). Steps are: 1) Resize to correct final size 2) Rotate 90 degrees 3) Flip horizontally 4) Invert image This conversion will run on a semi-embedded system. Conversion must run in a 128MB J2SE 1.5 JVM and complete in one minute on a Pentium III-800MHz (the test system I have for this). Source files will be between 100 and 200 MB. For example, source file could be 12000x12000 pixels. Converted file will be smaller, but will not maintain the same aspect ratio. Examples could be 10000x2500, 14000x2000, or 8000x3000. Pr...

...simply drawn to the screen a series of gaps gaps will be seen between the tiles. This is because the WIDTH of tiles will vary depending on the latitude. However the HEIGHT of a tile will always remain constant within a map set. The display function must sample the tile widths involved and distort each tile into a trapezoid so that they seamlessly meet at the edges. Coder will use a bicubic resample method to accomplish this. Distortions caused by extreme zoom-outs are acceptable. (4) Map viewer will be designed to work with map tiles of any size (up to 2000 pixels per tile). The buyer will test the coder's work using datasets with other tile sizes. (5) A black background will be used for image areas with no data. (6) Sample map tiles can be found at
