Background: Digital image processing and analysis are used for computer assisted evaluation of sperm morphology. Sperm head morphology has been identified as a characteristic that can be used to predict a male’s semen quality. On the other hand, zygote competence analysis is an importance tool to select embryo(s) for transfer. The aim of the present study is to determine zygote quality resulted...

Measuring the perceived quality of printed images are important to assess the performance of printers and to evaluate technology advancements. Image quality metrics have been proposed to objectively assess the quality of images, and new metrics are continuously proposed. However, applying these metrics to printed images are not straightforward, since they require a digital input. We present a n...

Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...

background: breast is one of the main radiological sensitive organs, hence it is important to evaluate absorbed dose to this organ especially to the glandular parts. it is the aim of this study to measure mean glandular dose and image contrast in terms of different mammographic parameters. materials and methods: in this study two mammography machines located at said-al shohada (giotto) and shah...

the quality evaluation of agricultural products is one of the key factors in promoting their quality. in this study, a method based on combined image processing technique and artificial neural network was presented. separation of touching almonds under different positions is a very important step in design of grading devices. in this study, an image processing algorithm based on extracting crit...

Image Quality Assessment plays an important role in various image processing applications. It is still an active area of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Image quality assessment means estimating the quality of an image and it is used for m...

Image quality metrics have become more and more popular in the image processing community. However, so far, no one has been able to define an image quality metric well correlated with the percept for overall image quality. One of the causes is that image quality is multi-dimensional and complex. One approach to bridge the gap between perceived and calculated image quality is to reduce the compl...

The complexity of an image tells many aspects of the image content and is an important factor in the selection of source material for testing various image processing methods. Databases of pictures or videos explained with subjective evaluations constitute basic ground truth for preparing, testing, what's more, benchmarking calculations for target quality appraisal. We propose a few criteria fo...

This 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 model (HVS). The subjective testing is based on human perception, the objective testing on a mathematical co...
