A new method of processing digital images consists of a numerical filter which suppresses normal features producing an enhancement of the abnormality. The resulting filtered image aids the observer in the recognition of the abnormality. The filter is developed from verified normal images in the computer memory. The enhancement of pathologic accumulations with respect to surrounding activity was improved on the average by a factor of 2.6 for 13 lateral brain images.
一种处理数字图像的新方法包括一个数字滤波器，该滤波器抑制正常特征，从而增强异常特征。所得的滤波图像有助于观察者识别异常。该滤波器是根据计算机内存中经过验证的正常图像开发的。对于13张脑部侧面图像，病理性积聚相对于周围活动的增强平均提高了2.6倍。
