Effect of Histogram Equalization in Face Detection Using Spatial Histogram Features
نویسندگان
چکیده
Many information of an object can simultaneously be conserved by histogram based features. Because of the different intensities of pixels and different lighting conditions in an image, histograms which are employed for extracting features are better to be first equalized. In this paper, the effect of equalization over the histograms used for feature extraction is studied. Experimental results over some face data sets show the efficiency of the proposed method in object detection problem.

Density-Based Histogram Partitioning and Local Equalization for Contrast Enhancement of Images
Histogram Equalization technique is one of the basic methods in image contrast enhancement. Using this method, in the case of images with uniform gray levels (with narrow histogram), causes loss of image detail and the natural look of the image. To overcome this problem and to have a better image contrast enhancement, a new two-step method was proposed. In the first step, the image histogram is...
متن کاملImproved Face Detection Using Spatial Histogram Features
In this paper, we improve an object detection approach using spatial histogram features, by applying classifier ensemble. The spatial histogram features can preserve texture and shape information of an object, simultaneously. We train a hierarchical classifier by combining cascade histogram matching and the combination of Multi Layer Perceptrons. The cascade histogram matching is trained via au...
متن کاملReal-Time Face Detection Using Illumination Invariant Features
A robust object/face detection technique processing every frame in real-time (video-rate) is presented. A methodological novelty are the suggested quantized angle features (“quangles”), being designed for illumination invariance without the need for pre-processing, e.g. histogram equalization. This is achieved by using both the gradient direction and the double angle direction (the structure te...
متن کاملSpatial Histogram Features for Face Detection in Color Images
This paper presents a novel face detection approach in color images. We employ spatial histograms as robust features for face detection. The spatial histograms consist of marginal distribution of color image information. Facial texture and shape are preserved by the spatial histogram representation. A hierarchical classifier combining histogram matching and support vector machine is utilized to...
متن کاملA Proposed Rdit Algorithm for Analysis of Face Verification in Videos in Image Database for Crime Investigation
In the face recognition most researches has considered about face detection and identification or a face detection and tracking, but best of our knowledge very few researches has focused on the face detection, identification and tracking. The combination of these three mechanism are been used in many real time applications .Here we consider one of the application as theft detection in real time...
