![]() Public _FnIn As String Public _FnOut As String Public _pixelF As PixelFormat 04-25-06: Added the References section.03-31-06: More explanations about the Hough algorithm.So, we only let points (x,y) vote that satisfy: The points on the bottom line have a lower neighbour that is white. ![]() For each text line, you can draw many lines with different angles through the letters:įor deskewing, only the bottom line is important. To save some time, the number of voting points is reduced. The algorithm is computationally expensive. Calculate the skew angle as an average of the alphas Find the top 20 (alpha,d) pairs that have the highest count in the Hough matrixġ3. Create a two-dimensional matrix Hough and initialize the values with 0ġ2.
