Diamond Mask Improved Sobel Edge Detector based on FPGA

Gurupal Singh Chawla ^[2] | Nitin Jain ^[9]

Abstract: This paper describes a new improved sobel edge detection method which can process images with improved performance. We have applied Diamond masking method on sobel kernel and gradients are processed horizontal and vertical wise where negative values are made absolute. Performance wise it shows better with respect to Sobel conventional and other industrial application. In our experiment we use 55 mask which represents 4 to 5 fold accuracy compared to other techniques also the processing time could be within the acceptance level. The Proposed architecture is implemented on FPGA devices and comparison results shows improvement of 3 to 5 fold of conventional.
