Patent ID: 8532389

Claim:
A method for the analysis of image data of letters of a language which consist of an array of individual pixels, wherein each pixel exhibits a current pixel value which describes the color or brightness information of the pixel, wherein the following steps are carried out: a) a determination of a priority value for each pixel of the array is made by fixing the pixel as a reference pixel and calculation of a pixel difference value of the current pixel value of the reference pixel with relation to the current pixel values of a previously defined group of adjacent pixels and a position factor, wherein the position factor is greater, the closer the pixel group is to a start pixel dependent on the language; b) a combination of the pixels used for the calculation of the priority value into one pixel group; c) a sorting of the pixel groups based on the priority value of the reference pixel; and d) saving and/or transferal of the pixel groups according to their priority in the priority array.
