We have analyzed the problems associated with matching regions among the pair of images over the large set of overlapping regions. It is being studied that, matching images by using regions having unstructured association can be a serious problem. In this research we propose a linear formulation technique, which is matching simultaneously, so that the matched area can have color similarity histogram,...
This paper present a novel algorithm for cartoon image segmentation based on the simple linear iterative clustering (SLIC) superpixels and adaptive region propagation merging. To break the limitation of the original SLIC algorithm in confirming to image boundaries, this paper proposed to improve the quality of the superpixels generation based on the connectivity constraint. To achieve efficient segmentation...
Nowadays information retrieval systems get more attention due to the increasing use of multimedia technologies. The information may be in the form of video, image, sound and/or text. Application of surveillance, digital libraries, web applications and various other applications that handle enormous volume of data essentially have information retrieval components. This paper demonstrates an image retrieval...
Since last few years, Content Base Image Retrieval (CBIR) system has got more attention from its generic to specific use. CBIR depends upon visual low-level feature extraction i-e color, texture, shape and spatial layout. In this paper, a Local Binary Patterns (LBP) has been employed for texture analysis of image and also it is compared with average RGB color image descriptor method. And then a complementary...
The primate visual system has an efficient mechanism for color processing, it can receive a constant color in varying lighting conditions, so that many algorithms has been proposed to model the visual system functionalities. The aim of this study is to develop a color perception model that can use the opponency mechanism found in the visual system as a classification method in order to compute a unique...
Color constancy is considered to be as the building block for computer vision applications, because color perception may vary based on type of illumination present in the scene. It's well known that human visual system has very efficient color constancy, so it was used as a source of inspiration for some color constancy algorithms. In this survey we present the most recent advances in color constancy...
Visualization plays an important role in the analysis of grid circuit topological structure. The traditional line visualization method based on geographical position usually contains such problems that the nodes density distribution is uneven and the lines are too complex to understand. Some other methods completely neglect the real geographic location information. In this paper, we propose a new...
Nowadays, Content Based Image retrieval (CBIR) has been one of the most interesting research areas among researchers of technology-giants and academic institutions. Various CBIR techniques in literature show that there are three key properties in image retrieval viz. color, texture and shape. In this paper a detailed classification along with the challenges and issues of CBIR techniques evolved during...
In recently years, in the era of multimedia technologies need for information/data retrieval systems getting more attention. The data might be image, video, audio and/or text files. Digital libraries, surveillance application, web applications and many other applications that handle huge volume of data essentially have data retrieval components. These data always include large-scale of independent...
Content Based Image Retrieval (CBIR) has been a challenging research area among researchers of both industries and academic institutions. Human can judge and respond by memory to obtain and locate the target image and relate it by specific object, but for computer vision it's a challenging issue to retrieve image from complex database that is difficult to balance with an efficient algorithm. Simultaneous...
Multimedia technology is known as the single repository source for information retrieval that includes images, audio and video. Nowadays, it is growing with tremendous amount in the field of communication technology. Traditional text based retrieval techniques of information retrieval are inefficient at searching user's intended information from the large multimedia database. To address this problem,...
Arrangement of description of any specific object have a pattern structure in image processing filed to analyze and observe a targeted object and declare as goal is a hot field of research. For a random situation complexity is going to increase when we have classes that specifies concurrently and co-relate with each other with complex database. With an algorithm to follow sketch and finalized as a...
Greendicator is an indicator system that enables wireless embedded sensing systems to output data encoded as LED pulses to be decoded and viewed on smart phones. The transmitter encodes the message to be displayed in the form of modulated light pulses emitted with an existing visible-light LED or other light-emitting devices such as IR, laser diode, or light reflector. The receiver uses a camera-equipped...
Efficient and effective image enlargement without distortion attracts numerous interests these days. This paper presents an image enlargement system for images with repetitive components. Based on repetitive components and seam filling, our system achieves distortion-free visual effect. Our system captures and extracts the repetitive components by MSERs. After which, we got the repetitive component...
We present a new scheme for video colorization using optimization in rotation-aware Gabor feature space. Most current methods of video colorization incur temporal artifacts and prohibitive processing costs, while this approach is designed in a spatiotemporal manner to preserve temporal coherence. The parallel implementation on graphics hardware is also facilitated to achieve realtime performance of...
3D object matching from cluttered scences is a great project. In order to reduce computational complexity, local feature must be extracted from a small number of keypoints with rich feature. In this paper, we present an algorithm for 3D object matching based on local feature combined with color. Keypoints should be detected first, and then calculate the quality for each keypoint, we choice these high...

In view of vehicles image on different background and light densities, this paper presents a license plate location algorithm based on combinatorial feature. Firstly, we propose to preprocess the image of license plate with traditional but rapid method. Secondly, we define some...
This paper presented a video moving object segmentation and tracking system based on the active contour and the color classification models. First, the active contour model is applied to segment the target object in the initial frame. From the segmented object, the object and background regions are extracted. Then the object and the background regions are separately clustered according to color feature...
To segment an object from its background image for advanced vision processing, this article presents a novel bio-inspired framework for image segmentation in complex nature scenes, which is a hierarchical system that mimics the organization of layered early visual area in primate visual cortex. The proposed methodology consists of two typical stages: the first stage is a parallel modular structure...
