How to use Fred's ImageMagick textcleaner script?

问题

I want to do OCR on some of my images, but images are not quite very impressive. So, for cleaning it I wanted to use Fred's ImageMagick Textcleaner script. Command that I gave:-

sh textcleaner.sh input_file output_file -g -e stretch -f 25 -o 20 -t 30 -u -s 1 -T -p 20

This is the arguments which Fred has given on website itself. I am also doing for same sample image. But I don't think so any of my options are working everything is by default. And I keep getting this error also

textcleaner.sh: line 177: type: textcleaner.sh: not found
usage: dirname path
usage: basename string [suffix]
       basename [-a] [-s suffix] string [...]

And At last I had to keep the files in same folder where my textcleaner script is. How can I make it global and give the absolute path to it rather than putting the files wherever textcleaner is.

回答1:

It's a bash script - it says so in the first line - yet you are trying to run it in sh - which is not bash. You need to make the script executable, by running

chmod +x textcleaner

then you can run it properly using:

./textcleaner ... arguments ...

That should make the error message go away. Then try showing us a sample image so we can try and see what the problem is.

In my ImageMagick scripts, the syntax is script name ...arguments... input output. So your command should be

bash textcleaner.sh -g -e stretch -f 25 -o 20 -t 30 -u -s 1 -T -p 20 input_file output_file
