# Local descriptor cores
|
|
|
|
|
|
The local image descriptor cores compute the energy, phase, and
|
|
|
orientation for every input image. The results are provided with signed
|
|
|
fixed point precision Q7.1 for the energy, and Q7.2 for phase and
|
|
|
orientation. The algorithm starts from a multi-orientation analysis
|
|
|
given by a set of Gabor filters. Cores are described in Handel-C and
|
|
|
achieve a throughput of 36fps for an image resolution of 800 by 600
|
|
|
pixels. Hardware details are described in \[1\].
