The presence of both caption/graphics/superimposed and scene texts in video frames is the major cause for the poor accuracy of text recognition methods. This paper proposes an approach for identifying tampered information by analyzing the spatial distribution of DCT coefficients in a new way for classifying caption and scene text. Since caption text is edited/superimposed, which results in artificially...
Based on the study of the workshop layout, aiming at minimizing "transportation distance", the mathematical model of the workshop layout is established, and the optimal design of workshop layout is achieved by using the genetic algorithm with penalty function. Through the calculation of a living example, the validity and feasibility of the algorithm is verified.
