Replicating Photoshop's filters and adjustments in code
... where broad topics or topics asking for links are closed. Do you know of a resource with descriptions of how to implement the various Photoshop filters and adjustments ? Or just plain has implementations of them? E.g. Chrome filter; Black and White adjustment. I'm not asking for the ...

Re: Detecting lines in image, rotating based on that line's angle
... height is 3112 pixels, and atan(1/3112) = 0.0184 degrees, I don't think you will get a precision much better than that. I think that's fine. In Photoshop we can only rotate to a hundredth of a degree, but in testing with ImageMagick, we're getting better results if we can get into the thousandths ...

Re: Convert 3D LUT to hald image
Hello, I'd like to repeat the question in the original request: Is there a tool that could convert the text format to a hald image? (not in Photoshop or GIMP, but via command line!) What I'd like to achieve is: apply an existing 3D LUT (.3dl or .cube text format) to an identity hald image generated ...

Re: Motion Blur removal
The "Photoshop" example, 0_degree.png, looks like a horizontal blur created by a constant straight line PSF, like an ideal camera motion blur. Windows BAT syntax: %IM%convert ^ rgb_000354.png ^ -define "convolve:scale=^!" ...

Re: Motion Blur removal
I do not know of any tool besides Photoshop that can remove camera shake (as opposed to the ideal motion blur that I have explained above) and one below. You have some references and can Google for others. That is all I know about it. I do ...

Re: Removal of coma from an image through cepstrum?
... towards the end of the topic. It might shed light on ways to compute and deblur your coma PSF. Also see the references within. You might also try Photoshop. They seem to have a deblur for camera shake. Perhaps that technique might help your case also. You might also try blind deconvolution. See ...

Re: Motion Blur removal
By the way, I believe Photoshop has some method of deblurring motion blur. But I have not tried to use it nor do they give any description of the algorithm that I have found. They seem to be able to estimate the motion blur by locating ...

Re: Recreate ImageMagick script to Photoshop Action
"for best quality, you need 32 bits/channel."
Someone mentioned to me that it would not matter because SVG filter would render only 8 bits per channel. Does it make sense?

Re: Recreate ImageMagick script to Photoshop Action
ImageMagick "identify" says your EXR files are 7500x7000 pixels but only 16 bits/channel. I have said that for such sizes, for best quality, you need 32 bits/channel. What setting do you recommend to use the file on the web? PNG 24? No. For web images, I recommend at least 16 bits per chan...

Re: Recreate ImageMagick script to Photoshop Action
My understanding is that Imagemagick only supports EXR "half-format" 16-bit floating point per pixel channel. But I only tried in Q16 HDRI. Perhaps Q32 HDRI will support the full EXR format. See http://www.openexr.com/index.html. You could use 32-bit floating point TIFF if in HDRI IM. See ...

Also, is your mug example image, a relative map? I am looking for a pixel perfect relative map so I can evaluate the my SVG fedisplacement filter accuracy

Re: Recreate ImageMagick script to Photoshop Action
... the relative map, so I can make another test with a MUCH better map! ; ) Can you send the map back in EXR? Then I can do the PNG export inside Photoshop. What setting do you recommend to use the file on the web? PNG 24?
