We propose a local bar-shaped structure detector that works in real time on high-resolution
images. It is based on the Radon transform. Specifically in the muti-scale variant, which is
especially fast because it works in integer mathematics and does not use interpolation. The
Radon transform conventionally works on the whole image, and not locally. In this paper we
describe how by stopping at the early stages of the Radon transform we are able to locate
structures locally. We also provide an evaluation of the performance of the algorithm running
on the CPU, GPU and DSP of mobile devices to process at acquisition time the images coming
from the device’s camera.
