| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Iterative shrinkage smoothing algorithm can perform image smoothing with eliminating fine details and preserving principal edges in an image. However, real time processing is difficult due to large processing time when input image size is large. By utilizing downscaled image of an input image, the processing time can be dramatically reduced. In this case, however, the information of preserved principal edges is not accurate. Considering the applications utilizing such edge preserving smoothing algorithms, such as image illumination compensation and detail enhancement, inaccurate principal edge information degrades the quality of resulted images. In this paper, we propose processing time reduction method of iterative shrinkage smoothing by utilizing parallel processing. Experimental results show that the frame rate increases as number of processes is increased. |
