Abstract
The FPGA implementation on Image Rotation algorithm is presented here. This implementation satisfied the real-time constrains and introduces a solution of very few distortions in image rotation. This design is based on Skew raster scan method of the original image. This design uses only integer addition instead of floating point multiplication. This solution also incorporates an arithmetic design that computes trigonometric value with precision up to 10 in rotation angle which improves the real-time performance rotation of gray level image. Thus the solution reduces the computational burden and improves the real-time performance.
