------------of graduation Project symmetry feature extraction of images

according to the symmetry characteristic to detect the obstacle, according to the general Qualitative analysis method , We can only know whether the obstacle is symmetrical , But it is not enough to use the qualitative analysis of symmetry , it must be able to be quantitatively described in mathematical form , and the quantitative analysis of symmetry is introduced. In this paper, the concept of continuous symmetry is used to establish a quantitative method to measure symmetry. A row of grayscale data in an image can be considered a one-dimensional function g (x)of horizontal pixel coordinates, ( we don't need to know what the function is, because we end up using this function value, which is similar to the sense of a kernel function ) Any function can be written as a even function
