How to recognize a batch of electronic thermometers reading is a key step in its qualified judgment. Using machine vision method to acquire the picture of batch electronic thermometers screen, adopt gray processing, edge detection and reclamation, gauss filter, precise edge localization, binarization processing and OCR recognition. Secondly obtaining the(More)
In cognitive radio systems, one of the main requirements is to detect the presence of the primary users' transmission, especially in weak signal cases. Cyclostationary detection is always used to solve weak signal detection, however, the computational complexity prevents it from wide usage. In this paper, a significant cycle frequency based feature(More)
