Abstract: Disclosed is a self-adaptive infrared image defringe algorithm based on a local median histogram. By calculating the scene complexity in a sliding window, a window having the minimum scene change between each column and an adjacent column in an original infrared image is found. A cumulative histogram of all columns of the window is calculated to obtain a median histogram of the central column of the window, corrected greyscale values of pixels of the central column of the window are calculated according to the median histogram, and the fringe value of this column can be obtained by subtracting a mean value of the corrected greyscale values from a mean value of original greyscale values. A final output greyscale value of this column is obtained by subtracting the fringe value from the entire column. In the present invention, an area where a scene change is not obvious in an image is found by means of a sliding window, a correction effect is not affected by the scene, and the problem in a traditional median histogram equalization defringe algorithm that new noise is introduced due to a drastic scene change can be eliminated.

Abstract: A resonant converter and a voltage conversion method. The resonant converter comprises a high-frequency inverter circuit (101), an inductor-inductor-capacitor (LLC) resonant slot network (102), and a hybrid rectification circuit (103), wherein the LLC resonant slot network is respectively coupled to the high-frequency inverter circuit and the hybrid rectification circuit. The high-frequency inverter circuit is used to convert a first direct current voltage into a first alternating current voltage. The LLC resonant slot network is used to adjust the first alternating current voltage to obtain a second alternating current voltage. The hybrid rectification circuit operates in a full-bridge rectification mode if a direct current voltage regulation gain is within a first threshold range, and operates in a voltage-doubling rectification mode, if the direct current voltage regulation gain is within a second threshold range, so as to convert the second alternating current voltage into a second direct current voltage to be output. The direct current voltage regulation gain is a ratio of the second direct current voltage to the first direct current voltage. The resonant converter and the voltage conversion method achieve high conversion efficiency of the resonant converter during power conversion in a wide input-output voltage range.
