FPGA Implementation of Filters in Medical Imaging

Real time analysis of images is an inherent expectation of the medical imaging research area. Monitoring of important medical data requires the acquisition of high-quality images at a high rate. Nowadays many experiments are conducted on multiwell culture plates to determine the influence of different physical and chemical conditions on a specific biological sample. Often the medical practitioners need to supervise the complete data acquisition process in order to ensure the collection of reliable data. For this reason, some pre-processing steps including noise removal, contrast enhancement and preliminary edge detection needs to be implemented in real time. Here in this work ewe review important contribution on the implementation of filters on FPGAs and report runtime of 8 ms for images sized 1000x1000 pixels when two or more filters are applied subsequently.
