Paper Abstract

A new method of contour and its characteristic feature extraction form noisy image is presented. For image smoothing, the image convolution with a Gaussian function has been used. Then an inflexion point of an image function in the direction of the image gradient vector has been used as a new contour definition. Behavior of this image gradient gives also the information about spatial orientation of contour segments used as invariant characteristic features. Thus, the angles between segments have been calculated by means of operations on the histogram of contour angles. The method application on a highly noised image has been used for illustration of proper method works.
