A Novel Metric Approach Evaluation For The Spatial Enhancement Of Pan-Sharpened Images

, 2012
Various and different methods can be used to produce high-resolution multispectral images from high-resolution panchromatic image (PAN) and low-resolution multispectral images (MS), mostly on the pixel level.

Predicting Face Recognition Performance Using Image Quality [PDF]

, 2015
This paper proposes a data driven model to predict the performance of a face recognition system based on image quality features. We model the relationship between image quality features (e.g. pose, illumination, etc.) and recognition performance measures

Quality Assessment of Stereoscopic Images

EURASIP Journal on Image and Video Processing, 2008
Several metrics have been proposed in literature to assess the perceptual quality of two-dimensional images. However, no similar effort has been devoted to quality assessment of stereoscopic images. Therefore, in this paper, we review the different issues related to 3D visualization, and we propose a quality metric for the assessment of stereopairs ...

Understanding How Image Quality Affects Deep Neural Networks

, 2016
Image quality is an important practical challenge that is often overlooked in the design of machine vision systems. Commonly, machine vision systems are trained and tested on high quality image datasets, yet in practical applications the input images can
