The paper proposes a novel image enhancement method based on histogram equalization called Quadrants Histogram Equalization with a Clipping Limit (QHECL). The proposed method consists of four steps: (i) The first step is to compute the median value of the input image, which is used to divide the input histogram into two sub histograms. (ii) We calculate the average brightness value of each sub histogram...
The reagent dosages can directly affect the concentrate grade and recovery in the mineral flotation process. For many years, the dosage has mainly been controlled by human observation of froth image features, especially the bubble size. However, the reagent dosage control based on human experience can easily cause fluctuation of the performance index, which may result in wasted ore resources and chemical...
Traditional group evaluation methods for complex simulation system credibility are always ignore the correlations among the evaluation indices and those among evaluation experts which lead to the evaluation result inaccurate. To address this problem, a new group evaluation method for complex simulation system credibility with the correlated assumption for evaluation indices and evaluation experts...
