Product Description
Photo-to-Sketch Transformation in a Complex Background
Abstract-In the first place, investigate the problem of sketch generation for sketch-based image retrieval (SBIR).Solving this problem is important to obtain better retrieval results, because a powerful feature extraction algorithm is inefficient. Transforming photos from raw pixels into pseudo-sketches closes the gap between these two domains and plays a significant role in SBIR. This problem is relatively challenging because of: 1) the complexity of the image background and 2) the complexity of the resulting edge map. Here develop a system to generate pseudo-sketches from photos. Saliency detection is used to extract the major objects from a photo. Then, a Gabor filter is designed to further capture the ‘‘real-major’’ object. Finally, the Sobel operator is used to obtain the final pseudo-sketch. Experiments are conducted using the Flickr15k data set. The results show that the obtained pseudo sketches are reasonable and that the SBIR process produces the state-of-the-art results in certain categories.
