This approach is based on double-background. We use the statistical information of the pixel intensity to construct a background that represents the status during a long time, and construct another background with feedback information in motion detection that represents the recent changes at a short time. This couple of background images is fused to construct and update the background image used to motion detection. The background reconstruction algorithm can perform well on the tests that we have applied it to.","PeriodicalId":367106,"journal":{"name":"Fourth International Conference on Image and Graphics (ICIG 2007)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115415943","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}

To recognize cells, one basic and hardest task is for cell delineation, and the cell clusters must be decomposed. In this paper, a novel algorithm based on shape information is proposed for splitting cell clusters. In the algorithm, it integrates morphological smoothing with holes filling in a pre-processing stage. Then the cell clusters are identified through a polygon approximation. Finally the cluster decompose is implemented, which consists of the detecting concave points on the contours and determining the decomposing lines. The algorithm can not only split the simple cell clusters, but also complicated clusters. In addition, this algorithm can be adopted for other applications, where separation between touching and overlapping particles is required.","PeriodicalId":367106,"journal":{"name":"Fourth International Conference on Image and Graphics (ICIG 2007)","volume":"63 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114040514","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}

The frame of this system is build, and simulating theory is studied in details, which mainly includes object- oriented modeling, modeling of virtual environment, modeling of human-computer interaction. In order to testify the theory, an experimental system considering the operator, computer, working machine, worked object, is given, which is integrated into closed loop by using mapping of human-computer and communication system. Here the interacting equipment consists of dataglove, Spaceball, shutter glasses, and virtual environment is modeled by using Worldtoolkit. While the real scene includes experimental fork that is the same scale as virtual working machine, barriers, worked object and other assisting facilities.

The blurred noisy image is assumed to be the output of a linear space-invariant system with an unknown point spread function contaminated by an additive noise. The scheme passes the blurred noisy image through a two-dimensional finite impulse response filter whose parameters are updated by the modified constant modulus algorithm with averaging and adaptive neuro- fuzzy inference system. When convergence occurs, the output of the filter is an estimate of the unobserved true image.

The identification of the lung structures is the initial stage in CAD for improving the detection sensitivity. This paper presents a novel automated lung segmentation method for nodule detection from CT images, using the information provided about motion of the tissue within the lung and pulmonary boundaries. A deformable image registration technique, optical flow, is used to detect the structures in magnitude to difference between two adjacent slices from a CT scan. Recent research has shown that L2 -type inner product introduces a pathological Riemannian metric on the space of smooth curves. Consequently, we refine our optical flow constraint in Sobolev metrics, which induce favorable regularity properties in gradient flows. Tests with real medical images demonstrate the method and its implementation.","PeriodicalId":367106,"journal":{"name":"Fourth International Conference on Image and Graphics (ICIG 2007)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127350399","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}

The measure used for detecting the shot boundary is not the mutual information itself involved in the frames of video sequences, but the absolute value difference between the frames, thereby the disadvantage influences resulted from the zoom of camera or movement of object are effectively eliminated. Moreover, the two-order mutual information is introduced into the shot boundary detection to make up for the scarcity of spatial information and fully utilize the relativity of gray-level between the adjacent pixels, and the detection effect is further improved.

Firstly, a band-stop filter method is adopted to remove the noises in high frequency. At the same time, a simply- thresholded original image is passed to Gaussian low pass filter, and outlines of fingerprint region are get by applying region growing method to the filtered image. Then, background in band-pass image is filled with outlines of the fingerprint region. After these procedures, background intensity is close to zero, thus fixed threshold one is used for binarization. Our experiment results demonstrate that band- stop method can eliminate noises effectively in the fingerprint images. And binarization in outline of fingerprint can solve the problem of disturbance of the background. Segmenting foreground from background helps select threshold and keep the characteristics of fingerprint.","PeriodicalId":367106,"journal":{"name":"Fourth International Conference on Image and Graphics (ICIG 2007)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131285462","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}
