In-Place Algorithm for Connected Components Labeling 10-22
Connected components labeling of a binary image is one of the most fundamental operations in image processing.  This paper presents two linear-time algorithms on this topics, one for just reporting the number of connected components and the other for labeling every element of value 1 (or white pixel) by its component index.

Optimal Parameter Selection Technique for a Neural Network Based Local Thresholding Method 69-94
Thresholding of a given image into binary image is a necessary step for most image analysis and recognition techniques. In document recognition application, success of OCR mostly depends on the quality of the thresholded image.
