Command to Check Drive for New Images

Desired Result: I wish to (1) have IM continually look to a folder that intermittently has digital images downloaded directly from a camera and (2) process those digital images per the subsequent commands. I currently am using drag-and-drop with the processing commands on a line within an "If" loop ...

Re: Lab colorspace - clipping

Is there a similar way to apply your suggestion using mean.r, mean.g, and mean.b to other statistical parameters, such as maxima, standard_deviation and kurtosis? I tried the identical approach (e.g. fx: maxima.r) with the first couple statistics and did not have success.

Re: Lab colorspace - clipping

Fmw42,
You were right about the colorspace converting correctly. Hopefully this does not cause issues in converting to Lab space; I'll try that next.

As always, thank you for your help.

Fmw42,
The color swatch I have been processing can be down loaded from:

Re: Lab colorspace - clipping

At the end, I will be starting with an RGB digital image from my camera, then converting the digital image to Lab space so I can compare tge Lab values a control image which I have had the Lab values determined with a colorimeter. As for sending the file, I will try e-mailing it to you and if that d...

Re: Lab colorspace - clipping

Fmw42, Update: I haven't been successful yet running the three line script you suggested in the post before last under Windows 7, but your single line suggestion in the last note looks much "cleaner", so I tried it. When I process a color swatch I created using Microsoft Paint having the rgb colors ...

Re: Lab colorspace - clipping

To fmw42: The file I am starting with is indeed a digital image of RGB format. In the script above, I was attempting to identify a simplified yet correctly functioning script to split channels independantly. When I'm able to do this, my intent is to convert the image using the -colorspace command, t...

Re: Lab colorspace - clipping

My goal of the script below is to separate each channel to determine the mean value; my plan is to build on this to convert to a Cielab colorspace and expand the fx:mean function so as to output the absolute Lab values into the table rather than the percentage values. If only one of the convert comm...

Re: Lab colorspace - clipping

Yes Snibgo, that worked perfectly. As to why I was using a loop within a loop, I tried everything including (apparently mistakenly) your last input. Now I'll try adding commands to (1) mathematically convert from percent Lab values to the absolute and (2) create a histogram of the 3 respective value...

Re: Lab colorspace - clipping

I have attempted to utilize you "SHIFT" suggestion in the following script on a Windows 7 machine. The script is generating output files as I hoped for using drag and drop, however it appears the script is not exactly right, as I never get to the PAUSE. Do you see any obvious errors? Also, I would l...

Re: Lab colorspace - clipping

Snibgo, I'm not having success with your suggestion and am still experiencing the looping. I would like to have the format of the bin file such that I can drag-and-drop multiple images having them all processed. I'm reading the forum and trying to utilize your suggestion in various was to make the s...

Fmw42, If you look at my post under "Possible bug reporting Lab colors as pixels: values" on 7/3/14 @ 22:03:37 and the following corresponding response(s) from Snibgo, I provided the inputs wrt 8 bit vs 16 bit and the corresponding calculated Lab outputs which Snibgo confirmed and helped with the wo...
