A Novel Image Retrieval Strategy Based on VPD and Depth with Pre-Processing
… restoration, color features extraction, and depth feature extraction. We propose a visual perceptual descriptor (VPD) to extract color features from an image. Gradient direction is calculated at each pixel, and the VPD is moved over the entire image to locate regions with similar gradient …
