摘要
the invention relates to a method for detection of partsthe right to a stream of digital data representing an image(m, n)in the identification of issues that defined each image contoursbythe module and the direction 8 of the gradient relative to a horizontal axis.according toin this process, we recorded the stream of digital data in the form of twosuccessive rows of n points p (i, j) each for each of the lines.extractin the n points of the line, and for each point (i, j))extractsaid point, we extract three coordinates belowpa (i-1, j - 1), pb (i, j), pd (i 1, j) direct neighbours of that point,comparein the direction of the point value of the pc withneighbouring points pa, pb and pd, and the values of the points and directions)the pd.the result of comparison is valid if the points of contours.and if thethe guidance values are close to each other. in addition, when the outcome of acomparison is validated, it copies the coordinates of the point of contactin the bottom of the connection point of contact information abovewecheck if the point pa (i-1, j - 1) is an outline of the four(pa)pb, pc, pd, extracts, and if so, the contact protectionpointorigin and the end point, and the direction of the line segment if its sizeisabove a predetermined threshold.
