A Proposed Scheme for Performance Evaluation of Graphics/Text Separation Algorithms

  title={A Proposed Scheme for Performance Evaluation of Graphics/Text Separation Algorithms},
  author={Wenyin Liu and Dov Dori},
We propose an objective, comprehensive, and complexity independent metric for performance evaluation of graphics/text separation (text segmentation) algorithms. The metric includes a positive set and a negative set of indices, at both the character and the character string (text) levels, and it evaluates the detection accuracy of the location, width, height, orientation, skew, string length, and the fragmentation of both characters and strings. Assigning a Segmentation Difficulty (SD) value to… CONTINUE READING
