Abstract: A system and a method for a computer implemented method of image enhancement includes the steps of receiving an input image, wherein the input image is a low light image, processing the input image, by a pre trained image enhancer, to generate an initial enhanced image, accessing, from an image memory, a response value corresponding to a sample specific property a normal image, generating an adjustment factor based on the response value from the image memory, generating a final enhanced image by applying the adjustment factor to the initial enhanced image.

Abstract: A system and a method for processing an image. The system comprises an image gateway arranged to receive an input image showing a scene composed by a combination of a plurality of image portions of the input image, wherein one or more of the plurality of image portions is associated with an exposure level deviated from an optimal exposure level; and an enhancement engine arranged to process the input image by applying an exposure/image relationship to the input image, wherein the exposure/image relationship is arranged to adjust the exposure level of each of the plurality of image portions towards the optimal exposure level; and to generate an enhanced image showing a visual representation of the scene composed by a combination of the plurality of image portions of the input image with an adjusted exposure level.

Abstract: A system and a method for assessing quality of a high-dynamic range (HDR) image. The system comprises a feature extraction module arranged to extract a plurality of frequency features on a pair of reference image and a distorted image generated based on the reference image; a comparison module arranged to compare a pair of feature maps obtained by processing the extracted frequency features on both the reference image and the distorted image; and a scoring module arrange to output an image quality assessment (IQA) score of the distorted image with reference to the reference image provided; wherein the plurality of frequency features are associated with sensitive information in a human visual system (HVS).

Abstract: A method for adaptive reconstruction of a compressively sensed data. The method contains the steps of receiving sensed data; conducting an initial reconstruction to the sensed data to obtain a plurality of first reconstruction patches; by a reconstruction module, conducting a progressive reconstruction to the sensed data to obtain a plurality of second reconstruction patches; summing the plurality of second reconstruction patches with the a plurality of first reconstruction patches to obtain final patches; and merging the final patches to obtain a reconstructed data. The progressive reconstruction further contains concatenating transformer features and convolution features to obtain the second reconstruction patches. The invention provides a hybrid network for adaptive sampling and reconstruction of CS, which integrates the advantages of leveraging both detailed spatial information from CNN and the global context provided by transformer for enhanced representation learning.
