Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...

Abstract A novel Intelligent Radar Detection Network (IRDN) is proposed to be able flexibly decompose and re-aggregate all functional elements in OODA cycle, so as establish a new kind of all-domain kill web featuring on-demand service, flexibility, scalability optimal channel, which can obtain maintain asymmetric air defense superiority with benefits from sensing, C2 strike capabilities.

A new method for line detection in two-dimensional image data is presented. Based on the moment-preserving principle, the method is developed to estimate line location and width to the subpixel accuracy within a circular mask. Experimental results are given to show the effectiveness of the proposed line detector.

Gradual transitions represent a challenging problem for temporal segmentation of video. Here we present two new features for detecting these. Recently, Ngo et al. set out a method for edge detection in spatio-temporal images made out of the central column (or row, or diagonal) of a video. A wipe generates a diagonal edge in such an image. In this paper we make use of all available pixels to gen...

Several authors have proposed algorithms for curve partitioning using the arc-chord distance formulation, where a chord whose associated arc spans k pixels is moved along the curve and the distance from each border pixel to the chord is computed. The scale of the corners detected by these algorithms depends on the choice of integer k. Without a priori knowledge about the curve, it is difficult ...

The aim of this paper is to show how image points can be extracted accurately. We will restrict our search to speciic points identiied by corners, which are stable given a sequence. Our approach makes use of a model{based corner detector. It matches a part of the image containing a corner against a predeened corner model. Once the tting is accomplished, the position of the corner in the image c...

In this article we present a novel approach to detect face in color images. Many researchers concentrated on this problem and the literature about this subject is extremely wide. We thought to decompose the overall problem into two intuitive sub-problems: the research of pixels have skin color in the original image and the analysis of pixels portions resulting, by means of a neural classifier. ...
