Abstract: Disclosed is a method for automatic classification of pathological images based on a staining intensity matrix. This method directly extracts the staining intensity matrix irrelevant to a stain ratio, a staining platform, a scanning platform and some human factors in the pathological image as the feature information of classification, without restoring normalized stained images, while retaining all impurity-free information related to diagnosis. It avoids the phenomenon that the diagnostic effect of the existing computer-aided diagnosis method of pathological images based on the traditional color normalization method changes with the changes of the selected standard pathological sections. Moreover, it avoids the error introduced by the need to restore the stained image, and has a higher diagnostic accuracy and a more stable diagnostic effect. At the same time, the method can realize the diagnosis of pathological images in a shorter time, which is easy to realize and more practical.

Abstract: A frequency hopping communication method for short-distance wireless communication between a primary device and a secondary device comprises switching by the primary device from the second frequency hopping sequence to the first frequency hopping sequence at a time point of frequency hopping switching, wherein M reserved channels are between a first frequency hopping sequence and a second frequency hopping sequence; and performing frequency hopping communication with the secondary device based on the first frequency hopping sequence.

Abstract: This application provides a low-power-consumption control method and a short-range wireless communication chip, and belongs to the field of short-range wireless communication technologies. The method includes: obtaining actual received signal strength indications corresponding to a plurality of historical receive slots; predicting, based on the actual received signal strength indications corresponding to the plurality of historical receive slots, received signal strength corresponding to a current receive slot; and adjusting a gain coefficient of a receive channel in a radio frequency front-end module in the current receive slot based on a predicted received signal strength indication. The radio frequency front-end module is coupled to the short-range wireless communication chip.
