Methods and arrangements for processing image data
The present disclosure provides methods and systems for processing data. One claim recites a method practiced using used a user's camera-equipped portable computer system. The method includes the acts of: capturing image data corresponding to a region using the camera of the portable computer system; applying a filter to the captured image data, in which the filter prioritizes image data at a center of the region and averages images data at a relative distance from the center region; and searching the filtered image data for hidden keys. Of course, other combinations and claims are provided as well.
1. A method practiced using a camera-equipped portable computer system, comprising the acts of:
capturing image data corresponding to a region using the camera of the portable computer system;
applying a filter to the captured image data, in which the filter prioritizes image data at a center of the region and averages images data at a relative distance from the center of the region;
searching the filtered image data for hidden keys.
2. The method of claim 1 in which the camera-equipped portable computer system comprises a smartphone.
3. A non-transitory computer readable medium comprising instructions stored thereon to cause one or more processors to perform the following:
capture image data corresponding to a region using a camera of a portable computer system;
apply a filter to the captured image data, in which the filter prioritizes image data at a center of the region and averages images data at a relative distance from the center of the region;
search the filtered image data for hidden keys.
4. A camera-equipped portable computer system, comprising:
a camera for capturing image data corresponding to a region;
memory for storing captured image data; and
one or more processors programmed for:
applying a filter to the captured image data, in which the filter prioritizes image data at a center of the region and averages images data at a relative distance from the center of the region;
searching the filtered image data for hidden keys.
5. A smartphone comprising the camera-equipped portable computer system of claim 4 .
