| 发明名称 | Method and system for generating output image data | ||
| 摘要 | A method of generating output image data comprises obtaining derivative data relating to a reference image; obtaining a constraint for output image data; and generating the output image data from the derivative data relating to the reference image in dependence on the constraint. This method can be used to recover a robust output image from the derivative of an input image. | ||

| 主权项 | 1. A method of generating output image data, comprising: obtaining derivative data relating to a reference image, obtaining a constraint for output image data, wherein the constraint includes minimizing the sum of: the difference between a derivative of the output image data and the derivative data for the reference image, and a penalty term that is the product of a constant and a magnitude of the output image data, wherein a value of the constant is inversely proportional to the magnitude of the output image data, wherein a value of the constant is inversely proportional to the magnitude of a function of the output image data; and generating the output image data from the derivative data relating to the reference image in dependence on the constraint. | ||
