Abstract: Shape recognition, is a major problem in image processing. It is used in many areas like detection of patterns, face recognition, medical field, space, manufacturing industry, defense etc. In search by image, search is done in the web or dataset by text based query only. Sketch based image retrieval(SBIR) is a young research area, which requires the image like hand drawn black and white sketch as input. Today we have plenty of resources to draw the sketches and we are proposing a novel method to compare these sketches with the images with in our dataset using Contour Detection by Chain Codes.
Keywords: Chain Code, Contour Detection, SBIR, Sketches.
