Abstract
Techniques for improved feature detection are described. In one embodiment, for example, a device may include a processor circuit and a feature detection module, and the feature detection module may be operative on the processor circuit to perform a first feature detection iteration for a graphics information element using an integral pixel value array, determine a scaling factor, recalculate the integral pixel value array based on the scaling factor, and perform a second feature detection iteration for the graphics information element using the recalculated integral pixel value array. Other embodiments are described and claimed.
