Keep seeing an interesting symbol appearing near my office (on car stickers and signs), it may be an Islamic icon or something, but it occurs to me that without text-based ancillary information, I have no idea of finding out what it means. Dunno if I'm handing away the idea that could have made my dotcom fortune here, but what about a search facility that matches the form of graphics and gives you the best match for your input?

It works something like this: take a big, constantly updated (by spider) database of gifs and jpegs from HTML pages - something like what Google's 'image search' uses. Set up a script to resample all these images to common dimensions. Then the user either uploads their 'search image' to the site (where it is resampled to comparable dimensions) or uses a little paint applet in the site to draw what they want to find. The 'search image' is then compared pixel-by-pixel with the image database and links to the source HTML pages returned in order of accuracy.

I believe there are routines available that have some success in recognising/comparing car registration plates, faces and stuff used by police forces and security bodies; I'm asssuming it would be pretty easy to do something similar for bitmaps. If colour involved too much data processing, we could start with grayscales.

Am I crazy? As a designer, I would use it. Should I take the patent out now and go to see my bank manager?

       Interesting idea. I doubt it would make you a fortune but it would be a useful tool if you could write it. The sheer number of shapes available could be a major problem though. Imagine how many results you'd get back when you searched for something roughly square-shaped.

       Image semantics recognition. Lots of people working on it, especially the big media asset management folks.

       Some sort of hasing algorithm; reduce the images to monochrome/greayscale and resize, then hash them and do a nearest-fit. Should work. Good idea. Croissant.

       Damn - looks like it's more baked than I expected.
