We present a biologically motivated classifier and feature descriptors that are designed for execution on single instruction multi data hardware and are applied to high speed multiclass object recognition. Our feature extractor uses a cellular tuning approach to select the optimal Gabor filters to process a given input, followed by the computation...
Curve detection is one of the fundamental steps in computer vision applications. Conventional edge detectors provide only an output of edge pixels; curve matching is then needed to fit edge pixels into curves. Despite having achieved some success, it suffers constraints for applications that require real-time and robust image analysis, such as robo...
This paper presents a perceptual organization based method for real-time license plate identification and tracking by video content analysis. In this method, video content is described using a set of perceptual shape features, called generic edge tokens (GET). A video frame can be represented as a GET map. Motion GETs (MGETs) are segmented from the...
Image region detection aims to extract meaningful regions from image. This task may be achieved equivalently by finding the interior or boundaries of regions. The advantage of the second strategy is that once a closure is detected not only its shape information is available, but also the interior property can be estimated with a minimum effort. In...
As an important metric for wireless ad hoc networks, network lifetime has received great attentions in recent years. Existing
lifetime-aware algorithms have an implicit assumption that nodes are cooperative and truthful, and they cannot work properly
when the network contains selfish nodes. To make these algorithms achieve their design objectives e...
Service composition is a powerful tool to create new services rapidly by reusing existing ones. Previous research mainly focuses
on the wired infrastructure-based environment. With the developments in mobile devices and wireless communication technology
in recent years, mobile ad hoc network has received an increasing attention as a new communicati...

... For example, in (Kamat and Ganesan, 1995) a system is proposed which is based on the Hough transform, and its implementation on a commercial Digital Signal Processor (DSP) is studied. Perceptual shape features called Generic Edge Tokens (GET) are used in (Chen et al., 2006) to describe and find the license plate, while the tracking relies on motion continuity to define the ROI where the search is performed in the subsequent frame. In (Angeline et al., 2011), a combination of isotropic dilation and connected component analysis is used to locate the license plates in the case of multiple moving cars. ...
... Service oriented methodology retains the benefits of component-based development. A lot of service oriented research is presented in [2], [4], [3]. It has an interface portrayed in a machine-process able format (especially Web Service Description Language-WSDL). ...

... Parks et al. [19] presented a CUDA implementation of a saliency system for detection and the HMAX model for recognition, both steps are 10 times faster compared with the original algorithms. Woodbeck et al. [20] presented a GPU implementation of a bio-inspired model-similar to the HMAX model-using the OpenGL framework that achieves speedups of up to three orders of magnitude. Note that these last three works are based on the HMAX model, a region-based visual feature system, which is similar to our proposed model called the AVC algorithm. ...

... Precisely, the target for this paper is to extract closed object contours in given images. The pretty contour extraction result can be used for diverse higher-level vision tasks, such as image segmentation [4,5] and object extraction [6]. Moreover, the accurate contour extraction methods are also important in practical applications, such as object contour extraction for industrial inspection [7], water area contours extraction in satellite images [8], bone contour extracted to derive bony landmarks in ultrasound images [9], seam contours extraction in weld images for seam tracking in robotic gas tungsten arc welding and gas metal arc welding [10], and laser cutting for children's cushion in the automatic production mentioned in the experimental section in this paper. ...
