A Two-Stage Automatic Color Thresholding Technique

Sensors, 2023
Thresholding is a prerequisite for many computer vision algorithms. By suppressing the background in an image, one can remove unnecessary information and shift one’s focus to the object of inspection.

Analysis of uncertain data: Smoothing of histograms [PDF]

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
We consider the problem of converting a set of numeric data points into a smoothed approximation of the underlying probability distribution. We describe a representation of distributions by histograms with variable-width bars, and give a greedy smoothing algorithm based on this representation.
