Method and system for analog/digital image simplification and stylization

模拟/数字图像简化和风格化的方法和系统

计算机程序产品包括处理器执行改进图像结构和一致性的方法和/或用于简化/程式化的指令。该方法包括:通过以下步骤输入图像:扫描图像;使用相机拍摄图像;和/或使用计算机的图像创建。多通道图像被转换为​​单通道图像,其被分离成高空间频率的第一图像分量和低空间频率的第二分量图像。第一和第二分量图像各自通过滤波形成以去除相应的上限和下限阈值频率之外的频率。增益乘法器被应用于滤波的第一和第二分量图像以控制细节放大。第一和第二分量图像各自在相应的上限和下限阈值频率下模​​糊。通过从增益相乘的第二分量图像中减去增益相乘的第一分量图像来产生改进的风格化合成图像。

A computer program product includes instructions for a processor to perform a method of improving image structure and coherence, and/or for simplification/stylization. The method includes inputting the image, by: scanning the image; image capture using a camera; and/or image creation using a computer. Multi-channel images are converted into a single-channel image, which is separated into a first image component—the high spatial frequencies, and a second component image—the low spatial frequencies. The first and second component images are each formed by filtering to remove frequencies outside of respective upper and lower threshold frequencies. A gain multiplier is applied to the filtered first and second component images to control detail amplification. The first and second component images are each blurred at the respective upper and lower threshold frequencies. An improved stylized composite image results by subtracting the gain multiplied first component image from the gain multiplied second component image.
