    “I spoke to him to cooperate after writing bad review, he agreed , then after few hours started making same troubles. Wasted so much of my time on this guy. He is good for nothing. A suggestion to employers : I would not recommend this freelancer for any one : Read below: Here is the original review : Its disgrace I hired this guy… he is completely unethical, cannot trust, real waste of time. No knowledge at all. He is a dummy freelancer I asked him to investigate my code , I mentioned its very confidential and it would cost my job if leaked, this guy took the code and started creating problems when I asked the status of work. He said he investigated the code, then I asked him to tell me what he investigated and to create a document on his investigation which is critical to my project, all of sudden he said he does not want work on the project, as he lied he investigated on the codebase. He did not do any work, wasted my time, frustrated me I do not recommend this guy to anybody. I regret I spent time with him, it looks like it's a team - a basket of deplorable team members acting as individual. He is Unethical, not secure , not trustworthy, no commitment , no knowledge and a cheater. I caution anybody who wants to hire this guy - be careful , he will steals your code, he is a lier , wastes your time. Freelancer should not encourage this kind of behavior developers I escalated this issue to [login to view URL]”

Affine Registration of 2D Point Pattern Image

This paper presents a novel algorithm for the problem of affine point pattern matching. After using a Whitening transformation, the two point patterns related through an affine transform are respectively mapped to the point patterns related through a rotation transformation. The novelty of the proposed algorithm is by introducing a new distance metric and a distortion degree of the affine transformation into the objective function to make it smooth and have relatively less local minimum.
