A Deep Learning Approach in the DCT Domain to Detect the Source of HDR Images

A Deep Learning Approach in the DCT Domain to Detect the Source of HDR Images

Although high dynamic range (HDR) is now a common format of digital images, limited work has been done for HDR source forensics. This paper presents a method based on a convolutional neural network (CNN) to detect the source of HDR images, which is built in the discrete cosine transform (DCT) domain...
