An automatic white blood cell differential counting system, called EBIS81, was developed, which consists of GLOPR (Golay Logic Processor), Main Control Computer (Z-2), digitizer and DMA part, Auto focus and Search part and Image display part. The assignment for the author in this group project was implementation of GLOPR, DMA and Image display part. GLOPR is able to transform an array of binary image data A into a new binary image data plane B. The value of each element in the new array is determined by the values of itself and its neighbors and logic function. Also, the new binary image data is categorized according to the subfield and subfield order. Depending on the subfield order utilized, a boundary may be expanded to form the convex hull or reduced so as to form the convex kernel, skeleton, or residue. The neighborhood configuration is a hexagonal module for connectivity of each element.
The digital image is transferred to two 64 x 64 8-bit RAMs with DMA control signal. One 64 x 64 8-bit RAM is used for luminance signal and the other is used for blue color signal.
The digitized image and the processed binary image are displayed by the 128x 128 4-bit pseudo color mapping dazzler. This display system is able to display four different images at the same time.
EBIS81 is used as a clinical instrument whose purpose is to classify white blood cell images. It may also be used for other binary image processing.
