I ran it through 'halftone filter' in ISIS standard image processing toolkit. You really need better scans though, or supply a greyscale image, that could be thresholded using a adaptive thresholding technique.

Re: Extract JPEG from JPG Compressed Tif
Thanks for the confirmation. It's probably workable, but obviously not ideal.

Extract JPEG from JPG Compressed Tif
Hi all I've used scantailor to process some images and it outputs the files in TIF (JPEG) format (LZW, deflate, packbit, none or JPEG) Can imagemagick extract the JPEG data and write to a JPEG file without having to re-compress the data within ? I.e. a lossless conversion from JPEG compressed TIF to...

Re: Croppign black border, improving speed
Is there anyway to crop the image and spit out the new image size and/or crop region in one operation ? I say this because i had been writing the crop region to text file like this : R:\001.jpg,3220x4460+1+1 R:\002.jpg,3260x4260+301+201 R:\003.jpg,3220x4460+1+1 R:\004.jpg,3260x4260+301+201 R:\005.jp...

Re: Croppign black border, improving speed
It seems that the command convert 0029.jpg -background black -deskew 60% -bordercolor Black -border 1 -fuzz 90% -trim c:\out.jpg Will actually perform the required operation much faster , so this is what I will go with unless there is a good reason not to use trim ? Do i need a +repage command ? tha...

Re: Batch script help (Windows)
Set it up to drag and drop a folder . Can be easier that way. So you script will look in the folder for *.jpg or whatever

Re: Croppign black border, improving speed
You are getting crop parameters, but then doing a "-deskew" before applying that crop. So won't the crop parameters be wrong? The "-border 1" will also make the parameters out (by 1). Ah yes the border will be adding the +1. I deskewed before the crop so that the rectangular pag...

Re: cat border resize resize/align
you might need to look at using openCV for this kind of thing. There's loads of tutorials out there for detecting grids/shapes/lines and then to transform them is one line of code

Re: jpeg file does not read in microsoft photo viewer
EMC Captiva Quickscan 4.5 Indeed, but either Quickscan is producing a faulty file that is readable by everything except Photo Viewer, or Photo Viewer is broken. Jusging by cursory internet searches there's a lot of people with similar problem and identical error message, presumably they aren't all u...

Re: jpeg file does not read in microsoft photo viewer
Brilliant. a Photo Viewer that doesn't view photos. Thats' the same message I was getting. I can't find any info on what they have changed and why that jpeg seems to be a problem./deemed insecure. (although Internet Explorer opens it )
