Lossless image watermarking for hdr images using tone mapping

Abstract: In this paper, a generic visible watermarking with a capability of lossless image recovery is proposed. This method based on the use of deterministic one-to-one compound mapping of pixel values a variety of visible watermarks on the cover image. The image conversion for watermarks normal image into HDR image are used in various image segmentation applications. During image conversion from watermarked into HDR image. The embedded watermark will be erased due to the usage of tone mapping in HDR image conversion. In this paper we have proposed a new technique for embedding a watermark which will not be erased during image conversion from normal image to HDR image. Our proposed system that, the original HDR image is transformed to a reference image by applying logLUV transformation. Finally the reverse log transform is applied to obtain the watermarked version of the given original image when a generic TM (Tone mapping) is applied to the watermarked HDR image, the watermark is still presents long as the assumption of similarly between the log transform and TM. The compound mappings are proved to be reversible, which allows for lossless recovery of original image from watermark image.

Intelligent terminal image conversion method, intelligent terminal and storage device

Abstract: The invention discloses an intelligent terminal image conversion method, an intelligent terminal and a storage device, and the method comprises the steps: receiving a first control instruction for carrying out head portrait type conversion on a video image, the first control instruction comprising a to-be-converted image type; Obtaining a three-dimensional coefficient of each frame of image of thevideo image; Converting each frame of image of the video image into an image corresponding to the type of the image to be converted through a three-dimensional model based on the three-dimensional coefficient of each frame of image; And synthesizing the image corresponding to the to-be-converted image type into a target video image. In this way, the head portrait of the video image can be replaced without rerecording the video.
