RL-SeqISP: Reinforcement Learning-Based Sequential Optimization for Image Signal Processing

AAAI 2024technical

Hardware image signal processing (ISP), aiming at converting RAW inputs to RGB images, consists of a series of processing blocks, each with multiple parameters. Traditionally, ISP parameters are manually tuned in isolation by imaging experts according to application-specific quality and performance…

Learning To Exploit the Sequence-Specific Prior Knowledge for Image Processing Pipelines Optimization

CVPR 2023poster

The hardware image signal processing (ISP) pipeline is the intermediate layer between the imaging sensor and the downstream application, processing the sensor signal into an RGB image. The ISP is less programmable and consists of a series of processing modules. Each processing module handles a subta…

Attention-Aware Learning for Hyperparameter Prediction in Image Processing Pipelines

ECCV 2022poster

"Between the imaging sensor and the image applications, the hardware image signal processing (ISP) pipelines reconstruct an RGB image from the sensor signal and feed it into downstream tasks. The processing blocks in ISPs depend on a set of tunable hyperparameters that have a complex interaction wit…
