I would like to generate a binary mask for streets from static maps. In case this helps, here is what I am ultimately trying to do. I have some aerial video which I am registering to a satellite image from google static maps. After registering the video to the map, I would like to overlay any street signs/labels to the map+registered aerial video.
My first attempt at doing this was to get a satellite image (maptype=satellite) and then a hybrid image (maptype=hybrid) of the same location. In theory, pixel wise subtraction of these two images and then thresholding should produce a usable mask. However, the hybrid and satellite images seem to be off by one or two pixels (despite using the same latitude/longitude for the map center), so this simple method does not work. Is there something in the API that could be used for this? -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
