<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi,<br>
<br>
I am extracting a slice out of a MR volume as an unsigned short for feature extraction. The dynamic range of MR volume varies with different volumes. So I calculate the minimum and maximum pixel values of the MR volume and set the pixels values within the dynamic
range using RescaleIntensityImageFilter. The problem I encounter here is that when the image is rescaled with complete range(0-65535) I see an image with low contrast, but when rescaled within the dynamic range I get a black image. The images were viewed after
saving it in png format. Kindly let me know if this is the correct way to set the dynamic range.<br>
<br>
With the low contrast image obtained after rescaling in full range, I calculate the histogram. Based on the histogram I would like to improve the contrast. I tried adaptive histogram equalization, but that does not give good results since there are some outliers
that are having higher pixel values than other part of the image. How can I specify to equalize the pixels between certain limits say between 5% and 95% of the histogram. I am new to ITK. Any pointer to a probable solution would be of good help.<br>
<br>
