I know it's odd, but imwrite command happens to change my image's pixel size. Does anyone have a proper explanation for this? Thank you

You should probably not be using imwrite for ArcGIS.
MATLAB has no default for pixel scale. Only a small number of image formats accept scale information for imwrite and if it is not provided by the user then imwrite does not emit it into the image. imwrite is rather restricted in the metadata it can write.

Hi, Sorry to bump into this thread but I have similar issue.
I am using some filters and I am feeding with an image of 50x50 pixels aprox, but the imwrite outputs a much larger file of 400x400 pixels aprox or so.
ITs frustrating cause I am trying to measure specific areas (in pixels) in both images but due to the resize...Its not apples to apples any longer.
Any help? thanks
