Symbol recognition via statistical integration of pixel-level constraint histograms: a new descriptor
Yang (2005) Symbol recognition via statistical integration of pixel-level constraint histograms: a new descriptor IEEE Trans Pattern Anal Mach Intell (IF: 20.8) 27(2) 278-81Abstract
A new descriptor for symbol recognition is proposed. 1) A histogram is constructed for every pixel to figure out the distribution of the constraints among the other pixels. 2) All the histograms are statistically integrated to form a feature vector with fixed dimension. The robustness and invariance were experimentally confirmed.
