Assma Azeroual, Karim Afdel . GPU Implementation of Faber Schauder Discrete Wavelet Transform using CUDA. International Journal of Computer Applications. 183, 42 ( Dec 2021), 1-8. DOI=10.5120/ijca2021921815
Faber Schauder discrete wavelet transform (FSDWT) has many interesting advantages in image and video processing owing to its simplicity and its multiscale-based theory. It preserves the pixel ranges, has arithmetic operations, and detects edges in multiscale representation. With the increase of image size and the real-time requirement of many applications, the FSDWT computation becomes complex and needs other techniques to deal with it. To solve this problem, the FSDWT is implemented in parallel on a Graphics Processing Unit (GPU) using Compute Unified Device Architecture (CUDA) code. The results demonstrate that the GPU-based FSDWT exceedingly outperforms the CPU FSDWT.
