ABSTRACT: The
meteorological measurement automatic temperature testing system has a defective
image. To solve the problem such as noise and insufficient contrast, and put
forward the research program for image pretreatment, the median filter, histogram
equalization and image binarization, methods were used to remove noise and
enhance images. Results showed that feature points were clear and accurate
after the experiment. This simulation experiment prepared for the follow-up subsequent
recognition process.
