Of the spatial enhancement methods, contrast-limited adaptive histogram equalization (CLAHE) has frequently been used in observer experiments. Hem-MiNGER et al. studied whether detection of simulated masses in dense mammograms could be improved with the technique and compared the effects of this... [Pg.81]

One of the most common operations done with the histogram is the histogram equalization it consists in the spreading of the various gray levels inside the full range ofvalues in order to showmore details. We can notice from Figure 5.6 that not all the possible... [Pg.62]

One of the most useful techniques is histogram equalization. In this the algorithm passes through the individual bands of the dataset and assigns approximately an... [Pg.57]

After converting each frame into the grayscale one, the histogram equalization technique was utilized to determine the thresholds for initially distinguishing various compositions. Figure 1 shows a grayscale frame extracted from the video image. [Pg.662]

The block diagram of the proposed Combined Preprocessing Method is reported in Fig. 2, where an initial step of Feature Extraction is highlighted. This operation is intended to determine a parameter, called clip limit f), which is necessary for the subsequent phase of Contrast Limited Adaptive Histogram Equalization (CLAHE) as in [17,18],... [Pg.108]
