Unlike the conventional CORDIC algorithm which has constant number of iterations, the proposed algorithm calculates the nearest predefined angle to the input phase at the beginning of every iteration and then rotates by an optimal angle. As it has variable iterations, the novel rotation strategy provides faster convergence speed that reduces the number of iterations with respect to the previous approaches. Further, the performance of the proposed algorithm is improved when compared with that of the conventional one at cost of the same maximum shift number. With a number of simulation experiments, the performance of the proposed algorithm is validated by the numerical results.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130650069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, tracking an accurate position of the guide wire in the coronary artery has become an important area. This paper proposes a guide wire tracking algorithm based on OAC (Open Active Contours). The method focuses on improving the accuracy of guide wires tracking in a single frame and the speed of the extraction of the position of guide wire. In image processing procedures, we integrate a multiscale-filter for vessel's image enhancement, a method of OAC based on edge detection for initializing the vessel's image and an algorithm for deforming and control of curves. A standard analysis is used to evaluate this method in the last part of this paper. And the results show that the accuracy rate is 95.3% from the clinical images.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123964093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a regional-based convolutional network to address the tasks of people detection in the crowded scenes. Unlike the traditional methods, we propose an end-to-end framework that uses the convolutional network for feature representation, which generates candidate proposals online and performs the location optimization simultaneously. By separately detecting the heads of people, our system gets rid of the problems caused by occlusion and achieves robust detection results in the case that no matter whether the head is towards or backwards to the camera. Experimental results show that it greatly outperforms traditional methods.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123369110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vanishing point plays a very important role in the machine vision based railway-environment surveillance methods, e.g. estimating the pose of the camera, video segmentation and panorama. In the application of railway-environment surveillance, we most care about the vanishing point corresponding to the lines parallel to the rails. Based on the prior, we design a fast and effective method-Selected Line Segment Detector (SLSD) to detect the line segments corresponding to the scene-lines parallel to the rails, and then use a cross-iteration method to find the vanishing point in the railway environment images. We give both theoretical analysis and algorithm implementation.

However, it may be not robust to describe an action by only a single MHI. Therefore, an action recognition scheme by using multiple key MHIs (MKMHIs) is proposed. Firstly, an adaptive method for key MHIs selection is proposed based on entropy of MHIs. Then a new combined feature vector of MHIs by spatial pyramid matching (SPM) is defined to describe spatiotemporal characteristics of actions. Here, the proposed solution is composed of SPM two dimensional entropy (2D-entropy) of MHI and SPM Zernike moment of motion history image edge (MHIE), and our combined feature is lower compared with Local Binary Pattern Histogram(LBP_H). At last, action recognition is performed by SVM and voting. Experimental results show the proposed method based on MKMHIs can improve the action recognition ratio.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124304305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we explore the issue of face anti-spoofing with good performance in accuracy by utilizing optical flow vector on two types of attacks: photos and videos shown on high-resolution electronic screens. The key idea is to calculate the displacement of optical flow vector between two successive frames of a face video and obtain a displacement sum of a certain number of frames. Under the circumstance of stable light, the sum of displacement differs from real access and other spoofing attacks. In this situation, we experiment on REPLAY-ATTACK, a common and popular face spoofing database which shows a good performance. We conclude that spoofing attacks and real faces have different optical flow motion trend that our method shows temperate guesstimate when facing with a broad set of face attacks.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124388147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the challenges in re-identification is cross view matching, where the gallery and query data belong to different views. This problem is difficult because the person's appearance varies greatly due to significant viewpoint and poses changes. In this paper, we perform Kernel Canonical Correlation Analysis (KCCA) for each feature type to project data from different views into a coherent subspace in which the correlations from different views are maximized with this specific feature representation. A similarity score between query and gallery images is derived from each subspace. Then the scores of different features are fused with query adaptive weights to reach a final decision. This scheme is different from current KCCA approaches which only learn one single subspace for all the features and ignore the diversity of multiple features. The effectiveness of the method is evaluated on two publicly available datasets (VIPeR and PRID), yielding state-of-the-art performance with respect to recent techniques.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124518832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
