An Apple II Based Image Digitising System for Use with Immunoelectrophoresis Plates

摘要

In order to undertake basic image analysis on -dimensional imunoelectrophoresis plates (2-DIEP) an image digitising system has been constructed using a 48k Apple II in conjunction with a Microworks DS-65 Digisector card which takes the video signal from a television camera in a specially constructed projection box. Accuracy and reproducibility are assured by averaging up to 16 scans and normalizing to a blank plate. Careful packing of the data permits the processing of a plate on a single Apple disk while the primary disk drive carries the system software. The plate image of 70 mm x 70 mm i digitized into an array of 128 x 128 pixels each with 64 intensity levels. *Copyright *c( Science and Engineering Research Council, 1982).
