1. A system for image segmentation, comprising:
a storage medium storing a set of instructions; and
at least one processor in communication with the storage medium, wherein when executing the set of instructions, the at least one processor is directed to:
obtain an image;
divide the image into a plurality of image blocks;
determine, for each of the plurality of image blocks, a compressed representation of one or more features of the image block;
group the plurality of image blocks into at least two different categories based on the plurality of compressed representations; and
extract a region of interest from the image based on at least one of the at least two different categories of the plurality of image blocks, wherein
for each of the plurality of image blocks, the compressed representation of the one or more features of the image block includes a set of binary codes; and
the plurality of image blocks are grouped based on a bit distribution in the set of binary codes.
