Description: research on against geometry attacks watermarking technology. A digital Watermarking scheme, which is based on combination of simple and reliable harries detector and image normalization, is proposed. The feather points remain holding after geometry attack. Applying image normalization to these non-overlapped circles which centered at the feature points, after that, we can determine area for watermark embedding. -research on against geometry attacks watermarking technology.

Description: The present report outlines the design, implementation and performance of the application of Hough
Transform (HT) to detect circles in arbitrary pictures.
Detecting circles in arbitrary pictures involves a two step process in this project. First, edges within the
image have to be detected then, by means of a voting mechanism the most probable circles will be
located.
Edge detection goal is to look for boundary locations that naturally happen between objects. Objects
normally have continuous intensity values therefore sudden changes in that pattern might indicate a
boundary condition. Changes of intensity in one direction can be calculated by the gradient operator
however, noise can alter meaningful edges. Convolution is then normally applied to account for a small
amount of smoothing, thus reducing noise.-The present report outlines the design, implementation and performance of the application of Hough

Description: Hough变换是图像处理中从图像中识别几何形状的基本方法之一。Hough变换的基本原理在于利用点与线的对偶性，将原始图像空间的给定的曲线通过曲线表达形式变为参数空间的一个点。这样就把原始图像中给定曲线的检测问题转化为寻找参数空间中的峰值问题。也即把检测整体特性转化为检测局部特性。比如直线、椭圆、圆、弧线等-Hough transform is image processing image recognition from the basic geometry of one of the methods. The basic principle of Hough transform is to use the duality of points and lines, the original image space, the curve given expression through the curve of the parameter space into a point. This put the original image in the detection of a given curve is transformed into a peak in the parameter space to find the problem. That is the test for the detection of the overall features into local features. Such as lines, ellipses, circles, arcs, etc.
