Image Compression is an application of data compression for digital images to lower their storage and/or transmission requirements.
Source: Variable Rate Deep Image Compression With a Conditional Autoencoder
The application of machine learning(ML) and genetic programming(GP) to the image compression domain has produced promising results in many cases.
Via an intensive literature study, this paper first introduces DCT and JPEG Compression.
We present PLONQ, a progressive neural image compression scheme which pushes the boundary of variable bitrate compression by allowing quality scalable coding with a single bitstream.
At a high level, neural compression is based on an autoencoder that tries to reconstruct the input instance from a (quantized) latent representation, coupled with a prior that is used to losslessly compress these latents.
While autoregressive models excel at image compression, their sample quality is often lacking.
Recently deep learning-based image compression has shown the potential to outperform traditional codecs.
As the existing HDR quality datasets are limited in size, we created a Unified Photometric Image Quality dataset (UPIQ) with over 4, 000 images by realigning and merging existing HDR and standard-dynamic-range (SDR) datasets.
Recent works on learned image compression perform encoding and decoding processes in a full-resolution manner, resulting in two problems when deployed for practical applications.
More specifically, we designed a compressor network with Refine-Net for coding residual signals and motion vectors.
Recent research suggests that generative adversarial networks have the ability to overcome this limitation and serve as a multi-modal loss, especially for textures.
