Abstract

Image resizing is a common technique used in image editing and processing to reduce or increase the image’s dimensions. The naive approaches, such as cropping or scaling, may result in image distortion or data loss. A more sophisticated method is content-aware image resizing, which employs algorithms such as Seam Carving. A path of connected pixels is called as seam. In Seam Carving the least important seam gets removed to increase or decrease the size of the image. The algorithm takes into account the image’s gradient magnitude, which represents the changes in intensity between adjacent pixels. This is used to calculate the importance of each pixel. But the issue with seam carving is the execution time delay. In this work, parallelization techniques such as CUDA, MPI and OpenMP are applied to improve the performance and speed. No significant speedup is achieved from MPI and openMP, 2x speedup is achieved from CUDA.
