BLOB-BASED FEATURE EXTRACTION
Chunyan Shi · Chinese Journal of Computers · 1997
This paper presents a new blob based image processing idea, and describes the algorithms of feature extraction based on the chain code of a blob. Compared with the traditional methods, the new idea conforms better with the way of human's observation of scenes. The algorithm presented here introduces knowledge in the early stage of the image processing period, so as to construct the searching space, reduce computation amount, and speed up the processing considerably.
