Product image search aims to retrieve similar product images based on a query image. While deep learning based features work well in retrieving images of the same category (e.g. “searching for T-shirts from all the clothing images”), they perform poorly when retrieving variants of images within the same category (e.g. “searching for uniform of Chelsea football club from all T-shirts image”), since...
Salient regions detection is becoming more and more important due to its useful application in image representation and understanding. The accurate detection of salient regions can reduce the complexity and improve the efficiency of image processing. In this paper, a visual attention model based on multi-scale local contrast of low level features is proposed. In the proposed model, a multi-scale transform...
We formulate the problem of salient region detection in images as Markov random walks performed on images represented as graphs. While the global properties of the image are extracted from the random walk on a complete graph, the local properties are extracted from a k-regular graph. The most salient node is selected as the one which is globally most isolated but falls on a compact object. The equilibrium...
In order to provide more efficient content-based functionalities for video applications, it is necessary to extract meaningful regions from scenes as perceptual oriented representation of video content. We present a novel approach for salient region extraction, and simple visual features bound to salient regions will better represent the video content in perceptual manner. Since perceptual saliency...
