Book ChapterDOI
Combined full-reference image quality metric linearly correlated with subjective assessment
TL;DR: A new combined image quality metric is proposed, which is based on three methods previously described by various researchers, which shows the strong linear correlation with the subjective scores without additional nonlinear mapping.
Journal ArticleDOI
Improvement of Image Binarization Methods Using Image Preprocessing with Local Entropy Filtering for Alphanumerical Character Recognition Purposes.
Hubert Michalak,Krzysztof Okarma +1 more
TL;DR: The image preprocessing methodology with the use of local image entropy filtering is proposed, allowing for the improvement of various commonly used image thresholding methods, which can be useful also for text recognition purposes.
Journal ArticleDOI
Combined image similarity index
TL;DR: To avoid the necessity of such mapping the nonlinear combination of three known image quality metrics is proposed and verified for seven currently available image quality assessment databases in terms of the linear correlation with subjective scores.
Journal ArticleDOI
Objective 3D Printed Surface Quality Assessment Based on Entropy of Depth Maps.
TL;DR: The automatic objective assessment of the surface quality of the 3D printed objects proposed in the paper, which is based on the analysis of depth maps, allows for determining the quality of surfaces during printing for the devices equipped with the built-in 3D scanners.
Book ChapterDOI
Colour Image Quality Assessment Using Structural Similarity Index and Singular Value Decomposition
TL;DR: As a good solution for the further research, the application of the HSV colour space is proposed instead of commonly used YUV/YIQ luminance channel or the average of the RGB channels.
