Figure 3. The typical output of automatic CD4 cell counting program based on pattern matching.

Figure 3

(a) library images of cell types (a total 50 different images), (b) matching values compare an obtained shadow image and cell library images, (c) result of cell shadow image recognition using four different types of library cell patterns. The detected cells were marked with color coding to each library image that they were best matched using standard pattern recognition matching methods in MATLAB.
