Elimination of Dense Coordinate Grid in Image
Li Li · Water Resources and Power · 2009
Because elimination of dense coordinate grid is an important way to improve curve vectorization,we proposed the method of eliminating dense coordinate grid for the Turbine's Characteristic Curves based on Hough transform and Line detection.The image is checked by canny algorithm.The stnaight line in image is detected by use of hough transform.The effect of real-value scalar to detection result is analyzed.The detected line is substracted from the original image.The experimental result shows that the elimination of dense coordinate grid method has better result.
