Studies of EGRET sources with a novel image restoration technique [PDF]
, 2007 We have developed an image restoration technique based on the Richardson-Lucy algorithm optimized for GLAST-LAT image analysis. Our algorithm is original since it utilizes the PSF (point spread function) that is calculated for each event.

Google's Cloud Vision API Is Not Robust To Noise
, 2017 Google has recently introduced the Cloud Vision API for image analysis. According to the demonstration website, the API "quickly classifies images into thousands of categories, detects individual objects and faces within images, and finds and reads ...

Analysis and Optimization of Noise Response for Low-Noise CMOS Image Sensors [PDF]
, 2012 CMOS image sensors are nowadays widely used in imaging applications and particularly in low light flux applications. This is really possible thanks to a reduction of noise obtained, among others, by the use of pinned photodiode associated with a ...

Penapisan Derau Gaussian, Speckle dan Salt&Pepper Pada Citra Warna
IJCCS (Indonesian Journal of Computing and Cybernetics Systems), 2011 Quality of digital image can decrease becouse some noises. Noise can come from lower quality of image recorder, disturb when transmission data process and weather. Noise filtering can make image better becouse will filtering that noise from the image and

Image denoising with multi-layer perceptrons, part 1: comparison with existing algorithms and with bounds [PDF]
, 2012 Image denoising can be described as the problem of mapping from a noisy image to a noise-free image. The best currently available denoising methods approximate this mapping with cleverly engineered algorithms.
