I am a PhD. candiate (and Fulbright grantee) at University of Florida Department of Computer and Information Science and Engineering, working under Dr. Jeffery Ho .

I could be contacted at moali at cise.ufl.edu

Research Interest

My research interests are Computer Vision, Machine Learning and Pattern Recognition. During course of my studies I have worked on many interesting vision problems, ranging from ranging from gender detection using faces to 3D reconstruction, using Sparse Representation for denoising and classification, to multi-image cosegmentation.

Recently I have got interested in Deep Learning and Big Visual Data; problems of using them and problems that could be solved using them.

Research

I am working on the problem of Multi-image Co-segmentation, that is segmenting out the object that is similar in the given set of images. Two important words here are "object" and the "similar". Most of previous works have looked into the problem by segmenting out similar region and have defined "similar" to be similarity in color. This similarity is represented as energy function and problem is formulated as engergy minimization problem. Such a structure does not allow more control over what we want to be segment out. We, on the other hand, are iterested in segmenting out "object" that might have similar color, shape or structure. For this we segment out each image at different speed, easy images get segmented out much faster than complex images (images with many objects and texture) and then after each iteration share information about the images. Thus helping segment out complex images from information we have gathered from the easy images.
