Most of the literature on image filtering using FPGAs focuses on the normal case when the window is completely within the image. The exception - when the window is partly off the edge of the image - is rarely considered. If not managed appropriately, handling these exceptions can take up more resources than the main operation. Efficient techniques are presented that manage the image borders by reusing...
The watershed transformation is a popular image segmentation technique for gray scale images. In this paper, we describe an implementation method of a watershed algorithm based on connected components on FPGA. In the watershed algorithm based on connected components, regular memory accesses by raster scans and irregular memory accesses using FIFO and stack are repeated. The irregular memory accesses...
