    • A coefficient learning apparatus includes a regression coefficient calculation unit for calculating a regression coefficient, a regression prediction value calculation unit for calculating a regression prediction value, a discrimination information assigning unit for assigning discrimination information for discriminating whether a target pixel belongs to a first discrimination class or a second discrimination class, a discrimination coefficient calculation unit for calculating a discrimination coefficient, a discrimination prediction value calculation unit for calculating a discrimination prediction value, and a classification unit for classifying the pixels of the image of the first signal into any one of the first discrimination class and the second discrimination class based on the calculated discrimination prediction value. The regression coefficient calculation unit further calculates the regression coefficient using only the pixels classified into the first discrimination class and calculates the regression coefficient using only the pixels classified into the second discrimination class.
    • 系数学习装置包括用于计算回归系数的回归系数计算单元,用于计算回归预测值的回归预测值计算单元,用于分配用于鉴别目标像素是否属于第一鉴别类别的鉴别信息的识别信息分配单元 或第二识别类别,用于计算鉴别系数的鉴别系数计算单元,用于计算鉴别预测值的鉴别预测值计算单元和用于将第一信号的图像的像素分类为任一个的分类单元 基于所计算的识别预测值的第一判别类别和第二判别类别。 回归系数计算单元还使用仅分类为第一判别类的像素来计算回归系数,并且仅使用分类为第二判别类的像素来计算回归系数。
