Hough变换在人头识别中的应用

Hough变换能识别各种形状的目标,而且有对不完整边缘具有鲁棒性的优点.本文详细论述了Hough变换识别圆形目标的原理,并将其应用于人头识别.首先对原图像利用Canny算子进行边缘提取,然后利用Hough变换找人头的中心,大量实践证明了Hough变换识别人头的良好效果.

The Application of Hough Transform in Human Head Detection

Hough Transform can recognize various form object, and has the advantage of detecting discrete edges. In this paper, the principle of Hough Transform is described in detail, and it is used to detect human head. First, the edge of the original image with Canny operator was picked up, then the Hough Transform was used to search for the center of human head. The practice proved its good effect in human face recognition.
