Quality assessment by region in spot images fused by means dual-tree complex wavelet transform [PDF]
, 2011 This work is motivated in providing and evaluating a fusion algorithm of remotely sensed images, i.e. the fusion of a high spatial resolution panchromatic image with a multi-spectral image (also known as pansharpening) using the dual-tree complex wavelet

Towards a Semantic Perceptual Image Metric
, 2018 We present a full reference, perceptual image metric based on VGG-16, an artificial neural network trained on object classification. We fit the metric to a new database based on 140k unique images annotated with ground truth by human raters who received ...

Blind full reference quality assessment of poisson image denoising
2014 IEEE International Conference on Image Processing (ICIP), 2014 The distribution of real camera sensor is well approximated by Poisson, and the estimation of the light intensity signal from the Poisson count data plays a prominent role in digital imaging. It is highly desirable for imaging devices to carry the ability to assess the performance of Poisson image restoration. Drawing on a new category of image quality
