WebMay 22, 2024 · The pre-processing module converts the collected frame data into histogram data, and the transmission module transmits the detection data to the network. The data receiving and processing equipment receives the detection data of each detector, and then conducts cumulative processing and issues a warning. Histogram equalization accomplishes this by effectively spreading out the highly populated intensity values which are used to degrade image contrast. The method is useful in images with backgrounds and foregrounds that are both bright or both dark. In particular, the method can lead to better views of bone … See more Histogram equalization is a method in image processing of contrast adjustment using the image's histogram.
