Each pixel in a monochrome image has its own value, a correlate of perceptual brightness or physical intensity. A numeric representation of zero usually represents black, and the maximum value possible represents white.
Example of a standard digital orthophoto stored as a simple monochrome image file consisting of 6094 image lines plus a single header line. Each line, including the header, is 5790 bytes in length. File size is 33.6 MB. M is equal to monochrome.
Assume the image is a 1-bit monochrome image. Check the resolution to make sure parcel boundary lines are connected. If not, you can use Image/Resize to downsample by 2 or more. You can also use Image/Despeckle a few times to remove noise.
Step 2.
[remote sensing] A technique normally applied to a single-band monochrome image for highlighting areas that appear to be uniform in tone, but are not.
Panchromatic - Imagery Single-band or monochrome imagery (TWS).
Pixel- Pixel element. The smallest resolution unit (NCRST).
Platform - Where a sensor is based, i.e., a satellite, aircraft, or other flying object (NCRST).
Further PNG file processing (e.g. quantization to 1 bit for monochrome images) can be done with 'pnmquant' of the netpbm tools.
