Restoration of Partial Blurred Image Based on Blur Detection and Classification

Figure 3

Results of blur detection. (a) Partial blurred images. The train in the centre of the image which lies in the first row is blurred artificially using 8-pixel 0-degree motion blur kernel; the other regions are clear regions. The plaque in the centre of the image which lies in the second row is blurred artificially using 8-pixel defocus blur kernel; the other regions are clear regions. The guideboard in the centre of the image which lies in the third row is blurred artificially using a blend blur kernel whose motion blur scale and defocus blur scale are 5 pixels and motion direction is 0 degrees; the other regions are clear regions. (b) Shi’s results. (c) Segmentation results. (d) Detection results based on image segmentation. (e) Final results after refining based on neighbour information.
