Curvature aided Hough transform for circle detection

作者：

Highlights：

• Curvature radius is adopted to improve the H-transform for circle detection.

• Curvature pre-estimation avoids senseless accumulation operation, work faster.

• The CACD is capable to detect circles of different radius in complex scene.

• “Statistic deviation” is defined to measure the saliency of circle center.
