Range scanners are used in various applications in industry. Therefore, various range scanners, based on different working principles are developed. Among these, scanners using stripe based triangulation are the most promising ones. Unfortunately, these scanners have problems in obtaining the range data of shiny objects (having highlights) under ambient light. In this study, we develop a stripe projection...
Content base image retrieval is an important research field with many applications. In this paper we presents a new approach for finding similar images to a given query, in a general-purpose image database using content-based image retrieval. Color and texture are used as basic features to describe images. In addition, a binary tree structure is used to describe higher level features of an image....
In this paper, an integrated video surveillance system for robust tracking is introduced. In the blob detection part, an optical flow algorithm for crowded environment is studied experimentally and a comparison study with respect to traditional subtraction approach is carried out. In the segmentation part, different algorithms are fused to develop a hybrid algorithm for stable segmentation, and validation...
This paper presents a method for contour lines recognition from scanned military topographical maps. It is a difficult process, since contour lines are always overlapped or intersected with others information, and aliasing and false colors induced by the scanning process. The proposed method overcomes these difficulties using a multi-step process. First, a segmentation feature set is developed to...
Person retrieval and indexing in video sequences is a challenging task for many multimedia applications. This paper proposes a new method that index the person based on the similarity. Firstly, the persons in a shot are detected and tracked through face detector and continuously adaptive mean shift algorithm. Then mid-level features such as clothes colors and voice are applied to represent the person...
