High Dynamic Range Image Display Using Level Set Framework

This paper presents a novel solution to the High Dynamic Range (HDR) image compression problem using level set framework. Using level set framework, this method separates the HDR image into detail and profile. Then it uses a global tone mapping function to compress the profile. Finally it produces a low dynamic range version of the image for display by adding the details to the compressed profile. This method is capable of compressing the dynamic range while retaining the detail in the final image of various HDR images in a short time. Keywords Level set method, sigmoid function, high dynamic range image display.
