mwimagefinder searches for image files in a folder (or folders) and their subfolders.
Unlike normal find/search programs, mwimagefinder does not relay on file extensions. It searches and identifies image files based on their internal structure. This is especially important in working with large sets of files without or with incorrect extensions.
The result of the program is a csv file with found files and their type, disk size in MB, pixel spacing and resolution in DPI.
##Motivation
The program was developed in a response to a growing need of working with large sets of images in a JPEG, TIFF and DICOM formats without extensions. Thus, using normal file search methods that rely on file extensions or filenames were rather impossible.
##Supported formats
mwimagefinder uses ImageMagick for identifying image files, thus it supports all formats supported by ImageMagick. There are over 100 major image formats. For complete list of the files supported see here.
Since ImageMagick format support depends on many external libraries (e.g. zlib) the best way to check which formats which are supported on your system is to use the following command:
identify -list format
##Example usage
Search for image files in the current folder. Save results in found_files.csv:
mwimagefinderSearch for JPEG files in the current folder and save results in /tmp/found_JPEG.csv:
mwimagefinder --file-type JPEG --csv-file /tmp/found_JPEG.csvSearch for JPEG and TIFF files in the current folder smaller than 5 MB:
mwimagefinder --file-type JPEG,TIFF --file-size -5Search for all image files in /media/dir1 larger than 10 MB:
mwimagefinder --in-dir /media/dir1/ --file-size 10Search for all image files in /media/dir1/ and /home/m/dir2/ of size between 2 and 8 MB:
mwimagefinder --in-dir /media/dir1/ /home/m/dir2/ --file-size 2-8Search for JPEG and PNG files in the /tmp folder and save results in /tmp/found_JPEG.csv"
mwimagefinder --file-type JPEG,PNG --csv-file /tmp/found_JPEG.csv --in-dir /tmp/Search for all image files in /media/dir1/ /home/m/dir2/. Save results in /tmp/results.csv:
mwimagefinder --in-dir /media/dir1/ /home/m/dir2/ --csv-file /tmp/results.csvSearch for DCM, TIFF and JPEG image files in /media/dir1/ and /home/m/dir2/. Save results in ./results.csv:
mwimagefinder --in-dir /media/dir1/ /home/m/dir2/ --csv-file ./results.csv --file-type DCM,TIFF,JPEG Fast (using only file signature, thus no pixel size nor resolution is detected) search for image files in the two folders:
mwimagefinder --in-dir /media/dir1/ /home/m/dir2/ -fThe csv file shown below was a result of searching JPEG and DCM files in /media/sf_D_DRIVE/ and in "/home/m/dcm_for_tests"
