Research Experience:

• Patch Matching [Adobe Research Intern Expo Poster][Sample Video, Video 2]: During my Adobe summer internship, I worked on a new selection/segmentation tool based on patch matching. The intuition is much similar to "Pseudo-polar based estimation of large translations rotations and scalings in images" but instead of comparing images, we compare patches. The selection results are remarkable, yet it suffered large computational time. Thus, it is not ready for industry use yet. While at Adobe, I intensively learned about Coherency Sensitive Hashing, The Generalized PatchMatch Correspondence Algorithm and of course Fourier transform. After the internship, I did additional evaluation against PatchMatchGraph: Building a Graph of Dense Patch Correspondences for Label Transfer. That's why I became expert with Darwin Framework.


• Texture Classification: I worked on a new texture classification approach classifying textures suffering a dark shadow. The results achieved was not good enough for a top conference. Yet, I reviewed the literature in great details. I implemented both local binary pattern (LBP) and various filter banks like Leung-Malik, Schmid, and maximum response. I got familiar with compressed sensing for texture classification. I ran my evaluation experiments using the following texture datasets:  CUReT, UIUC and DTD.


• Image Segmentation: Developed an approached for solving interactive image segmentation problem. The approach supports different user annotation forms like scribble, complete and incomplete trimaps, tight contour and bounding box. Qualitative and quantitative results are compared against Grabcut, Geodesic Star Convexity and MILCut.

P.S.

I spent some time after earning my Bsc developing mobile apps for iOS. I co-founded Inova, a software development company. If you want to know more about such period. plz visit my personal site.
