Abstract: Appearance and application of the electronic imaging sensor during second half of the 20^th century, and tremendous growth in use of digital images in 21^st century, cause development of the new techniques for image acquisition processing, transmission and reproduction. In addition, the huge amount of data contained in digital image required development of the different compression techniques. All these processes introduce degradations in the image quality. In most cases the images areintendedto be used bya human observer, so human vision perceptual capabilities appears as key criteria for image quality assessment. The human visual perception models are reviewed in the paper. The imaging application in the different areas as digital cinema, medical imaging, and military target acquisition requires different image quality criteria development. The selected image and imaging system properties (size and field of view, image brightness, contrast ratio, resolution and MTF, noise) are reviewed. Image quality assessment could be done through objective laboratory measurements or using various computational techniques. The suitability of the different image quality assessment techniques for various applications is discussed.
