Simultaneous Fidelity and Regularization Learning for Image Restoration
Dongwei Ren, Wangmeng Zuo, David Zhang +2
Most existing non-blind restoration methods are based on the assumption that a precise degradation model is known. As the degradation process can only be partially known or inaccur…
SVM and ELM: Who Wins? Object Recognition with Deep Convolutional Features from ImageNet
Lei Zhang, David Zhang
Deep learning with a convolutional neural network (CNN) has been proved to be very effective in feature extraction and representation of images. For image classification problems,…
Fast Tracking via Spatio-Temporal Context Learning
Kaihua Zhang, Lei Zhang, Ming-Hsuan Yang +1
In this paper, we present a simple yet fast and robust algorithm which exploits the spatio-temporal context for visual tracking. Our approach formulates the spatio-temporal relatio…
A Local Active Contour Model for Image Segmentation with Intensity Inhomogeneity
Kaihua Zhang, Lei Zhang, Kin-Man Lam +1
A novel locally statistical active contour model (ACM) for image segmentation in the presence of intensity inhomogeneity is presented in this paper. The inhomogeneous objects are m…
Collaborative Representation based Classification for Face Recognition
Lei Zhang, Meng Yang, Xiangchu Feng +2
By coding a query sample as a sparse linear combination of all training samples and then classifying it by evaluating which class leads to the minimal coding residual, sparse repre…
Re-initialization Free Level Set Evolution via Reaction Diffusion
Kaihua Zhang, Lei Zhang, Huihui Song +1
This paper presents a novel reaction-diffusion (RD) method for implicit active contours, which is completely free of the costly re-initialization procedure in level set evolution (…
