PromptCIR leverages the powerful transformer-based backbone with the dynamic prompt module to proficiently handle blind CIR tasks, winning first place in the NTIRE 2024 challenge of blind compressed image enhancement track. Extensive experiments have validated the effectiveness of our proposed PromptCIR. ...
Blind quality enhancementCompressed images Resource-efficientEarly-exitLossy image compression is pervasively conducted to save communication bandwidth, resulting in undesirable compression artifacts. Recently, extensive approaches have been proposed to reduce image compression artifacts at the decoder side; ...

Specifically, 1) the discriminator requires a more powerful capability to dis- criminate realness from complex training outputs, while the gradient feedback from the discriminator needs to be more accurate for local detail enhancement. Therefore, we improve...
Stimuli Numbers were recorded by a female speaker and compressed to a fixed duration of 350 ms. using Wavelab 4.0. Auditory intensity of large (8 and 9) and small (1 and 2) numbers was equivalent (70 dB.). Lateralized auditory targets were presented using dichotic listening: a target sine...
Since to deliver raw image greatly challenges storage and transmission bandwidth, it's necessary to have digital images compressed. JPEG2000 is discrete wavelet based still-image compression standard proposed by Joint Photographic Expert Group (JPEG). Taking advantages of discrete wavelet transform (DWT...
Since different attacks tend to target different parts of the frequency spectrum, in this paper we propose a framework for blind watermarking which determines the type of attack that the image has gone through before extracting the watermark. Within this framework, we propose an attack classification...
