Traditional particle filter cannot accommodate to the environment of background interferences, illumination variations and occlusions. This paper presents a face tracking method with fusion of color histogram, contour features and grey model based on particle filter. First, it brought in contour features as the main cue of multiple features when tracking the face without stable color histogram....

Video enhancement approach aiming to achieve high qualities in entire video. Proposes a Superimposing algorithm for improve quality of intraframe based on multiple regions-of-interest and create piecewise tone mapping curve for entire frame, interframe constraints to improve the temporal quality consistency and based on result extract histogram. Two step are used for object quality retrieval (i...

This paper presents an estimation method of environmental sound sources localization based on MUSIC method by small-sized microphone array. MUSIC spectrum depends on array manifold vector calculated from microphone array configuration and eigenvectors provided an observed signal. By considering the relation between a microphone array and MUSIC spectrum, we examine the arrangement of microphones...

In this paper a novel multilevel thresholding method is proposed based on selecting the consistent peak of correlation function over the interested histogram region. The histogram is separated into two more regions up to the cost function is reached minimum. In the separation process of the histogram, a novel dichotomisation method is used. In general, correlation function of an image histogram...

Histogram equalization is widely used in different ways to perform contrast enhancement in images. In this paper, a new Histogram modification algorithm is proposed for contrast enhancement of images. Histogram Equalization (HE) is one of the most popular technique used for digital image enhancement, but it is not suitable to be implemented directly in consumer electronics, such as television, ...

The breast cancer is the second leading cause of death in women. The most effective method for detection of early breast cancer is mammography. Based on histogram equalization, this paper proposes the method to adjust histogram value in mammography picture to improve the result to identify of breast cancer. The proposed method to adjust, the histogram are adaptively increasing the value of hist...
