Questions related to Image Quality Assessment
Can you give me a solution about how to export high quality figures from MATLAB Simulink for inserting in MS Word. The generated circuit line in Simulink needs to be clear and bold that preferable for publication. After Drawing the circuit by default setting seems lines are very thin after COPY.
Looking forward to hearing from you.
I was wondering if someone knows how to infer the results of a BRISQUE or NIQE score for a particular image.
For example, in CIELAB color difference, a Delta E less than 2 is considered to be imperceptible.
Do we have similar or related perceptual inferences for BRISQUE and NIQE scores as well?
I understand that a lower score is better but I am looking for the perceptual impact of these scores.
For example, what is the impact of 1 unit NIQE score or 10 units of BRISQUE score?
I am testing images of a same scene taken with two different cameras to test their image quality.
I would appreciate if you could provide some references for the same.
Thanks in advance
I am currently developing a mammography phantom that has an MTF edge portion. The MTF portion is used to test the resolution of the digital mammography unit. My MTF is made of stainless steel with a thickness of 0.8mm and a dimension of 40mm x 40mm.
After exposing the phantom, I have an image of the MTF (a square object with very high attenuation compared to the background). I don't know what the next step is, analyze it or determine the MTF from that image. I just know that you need to put the ROI between the edge and the background. Is there a way I can manually determine the MTF edge of the system? Can you provide me an article or steps on how to do so. Or do I really need software to do determine the MTF? What software can I use to determine the MTF edge? Can you suggest software and the steps on how to determine the MTF from that software.
My alternative way of measuring the MTF of the system is to use a high attenuating material and bar pattern materials. So this MTF is made of a copper sheet (0.2-mm thick), a copper wire that forms 2lp/mm and 4lp/mm, and a transparent area (PMMA). I got this from IEC, and the method of determining the MTF is easy. But this kind of configuration is not used in any commercialized mammography phantom. Most commercialized mammography phantoms used MTF edge. That's why I prefer the 1st MTF configuration.
Do you know the difference between MTF edge and MTF bar pattern?
I really appreciate any help you can provide. Thank you!
How to evaluate the quality of an enhanced underwater image, where the ground-truth image is not available?
The image quality assessment is categorized into full reference (FR), reduced reference (RR), and No-reference (NR). In FR method, the reference image needs to available to be compared to distorted image.
Can a loose metalic object, from a patients pants or so, affect the homogeneity of the magnetic field? And affect the quality of the image, if it's stuck to the scanner while scanning?
Thank you :)
I want to measure strain in my sample by comparing their IQ map with undeformed sample's IQ map in aramis software,but need help about how to do this offline.
After getting RGB images from a hyperspectral image using 5 different techniques, how can one represent the quality of results quantitatively? A quick and handy solution is required.
