Composite description based on Salient Contours and Color information for CBIR tasks.
IEEE Transactions on Image Processing(2019)
摘要
This paper introduces a novel image descriptor for content-based image retrieval tasks that integrates contour and color information into a compact vector. Loosely inspired by the human visual system and its mechanisms in efficiently identifying visual saliency, operations are performed on a fixed lattice of discrete positions by a set of edge detecting kernels that calculate region derivatives at...
