Due to the uncertain, diverse, and light-attenuating characteristics of underwater environment, images have low contrast unclear problems. This paper proposes a histogram equalization algorithm based on optimized adaptive image quadruple segmentation cropping (AQSCHE). Compared with traditional enhancement algorithm, this introduces technology. Using exposure value point calculation formula tha...

An image quality matrix provides a significant principle for objectively observing an based on alteration between the original and distorted images. During past two decades, novel universal assessment has been developed with ability of adaptation human visual perception measuring difference degraded from reference image, namely structural similarity index. Structural since widely used in variou...

background: mammography is the primary imaging technique for detection and diagnosis of breast cancer; however, the contrast of a mammogram image is often poor, especially for dense and glandular tissues. in these cases the radiologist may miss some diagnostically important microcalcifications. in order to improve diagnosis of cancer correctly, image enhancement technology is often used to enha...

introduction: in today’s competitive environment delivering high quality service is the key for a sustainable competitive advantage. customer satisfaction has a positive effect on an organization’s profitability. satisfied customers form the foundation of any successful business because customer satisfaction leads to repeated purchases, brand loyalty, and positive expression of satisfaction to ...

Abstract—This paper presents the comparative analysis of various quality metrics for medical image processing. Measurement of image quality is important for many image processing applications. Image quality assessment is closely related to image similarity assessment in which quality is based on the differences (or similarity) between a degraded image and the original, unmodified image. Objecti...

background & aim:  the aim of this study was to evaluate and compare the relationship between body image and quality of life in female patients with breast cancer and healthy women. methods:in the current descriptive, causal, comparative, cross-sectional study, 50 women with breast cancer, referring to the radiotherapy and oncology clinic of imam reza hospital (mashhad, iran) and 50 healthy wom...
