Abstract :
A method for the processing of digital images using a two-dimensional LMS adaptive filter for noise reduction and subsequent edge detection is presented. This is implemented on a parallel virtual machine (PVM) consisting of inexpensive PCs (network of workstations, NOW). The experimental results for different image sizes and system configurations show close to linear speedup. Experiments to test dynamic load balancing are also performed.
