Clean-Border Fourier Descriptor for Image Shape FeatureExtraction

Shape is a visual feature which contains intrinsic high-level semantics, and has a greatapplication value in CBIR (Content-Based Image Retrieval) and IR (Image Recognition).There are many descriptors for shape feature. Fourier descriptor predigests ۲-demensionalimage information to ۱-demensional signal and be used widely. In fact, the shape of naturalimage is often messy and noisy. So, this paper proposes a preprocessing method which canclean the noisy shape image, and then researches and analyses the shape feature extractionwith Fourier descriptor method with an experiment
