this paper describes a novel method for retrieving 3D models. Following the principle of compound-eye vision, the proposed method represents a 3D model as a spherical image, and discriminates different 3D models using their corresponding spherical images. Meanwhile, by borrowing the concept of the Scale-Invariant Feature Transform (SIFT) algorithm, we design a feature extraction algorithm, named Spherical-SIFT, for extracting the salient local features on spherical images. Moreover, the Bag-of-Features approach is employed so as to achieve efficient comparison of different 3D models. the experimental results show the superior performance of our method over pervious methods.

the presence of artificial objects in radiographic images is common. For example, 33% of chest radiographs contain catheters. Anomaly detection algorithms used to monitor disease progression should not be confused by artificial objects such as catheters, chest tubes, pacemakers or even cloths that might be present in chest radiographs. Hence, the detection and the removal of artificial objects via a preprocessing module are very useful for computeraided Diagnosis (CAD) research. In this paper, we propose a Convolutional Neural Network (CNN) architecture that works as a trainable filter that removes simulated chest tube figures from chest radiographs.

Mesh-free deformation is an effective method for the simulation of deformable objects and characters in computer animation. It bears the merits of flexible control, good accuracy and easy implementation. Similar to other physically-based deformation techniques, however, computational cost remains a pressing issue, especially for large scale problems. Based on our previous work, in this paper we investigate the underlying structure of the numerical approach in order to speed up the computation. three algorithms are presented and their efficiency and convergence are analysed Our results show that we are able to significantly reduce the computation time and memory usage with little loss in accuracy. the new technique is capable of achieving interactive frame rates with large models.

this scheme describes a procedure that uses the motion characteristics of the videos to calculate the embedding tolerance for imperceptible video watermarking in wavelet domain. this procedure exploits the perceptual properties of HVS and motion content of video sequence adaptively calculating the embedding tolerance of watermark in order to improve the imperceptibility of watermarking according to the content of video. the experiment results indicate that this method can effectively reduce the degradation in the video quality.
