BMP Deinterlacer

BMP Deinterlacer is a small, simple and reliable command-line program that operates on 24-bit BMP files, and supports batch mode.

This has been provided in response to several requests for deinterlacing of a non-lossy format. Source code is included in the zip file.

Usage 1: bmpdeint [options] infile [outfile] If outfile is omitted, the output will be placed in a directory called deint (created if necessary) under the current directory. The output file will have the same name as the input file.

Usage 2: bmpdeint [options] -b dir

All BMP files in the specified directory will be processed and the resulting processed BMP files will be placed in a directory called deint (created if necessary) under the current directory. The output files will have the same names as the corresponding input files.

Note that you should never specify "*.bmp" or any other file(s) in batch mode. Specify only the source directory. To denote the current directory, use ".".

The default threshold and denoising are fine for most applications. Use the -c option to see the effects of tweaking the threshold. Areas shown in red under the -c option will be deinterlaced by interpolation; all other areas are passed through as is.
