概要

In the past, a lot of studies were carred out regarding the subjectively evaluations of images. (for example, ROC analysis, etc.) However, if you need to indicate a complicated potential of your ability, you will not be able to simply indicate it and not easily understand it. In the present paper, we could simply indicate a lot of information. Also, we restudied data (analyzed by ROC) using the Type 2 Fuzzy sets. When we converted images of the radiographs after digitization (same gradient processing, double gradient processing and quadruple gradient processing of the images), we were able to carry out some psychophysical experiments. The results were the same as the ROC analysis. Detectabilities were most improved using double gradient processing. This new evaluation will malce it easy to perform other psychophysical experiments, because it can indicate a lot of information on a graph.
