Human Visual System, Model, Image Quality
The article deals with evaluation of image quality by various methods and comparison of their results. Generally, there are several ways how to assess image quality. Three main approaches are: subjective testing, objective testing and image quality evaluation using a human visual system (HVS) model. The subjective testing is based on human perception, the objective one on mathematical computing and the human visual system models on mathematical modelling of human vision respecting features of the human perception. Then, the described methods and two designed models of HVS are used for image quality evaluation on a set of images. Results of the modelling were compared with results of the subjective and objective methods.
