Abstract: A radio frequency (RF) generator incorporates an automatic level control (ALC) circuit to control the output level of the RF signal where the ALC circuit implements synchronized ADC sampling, pulse sample indexing, gated accumulation to enable fast ALC loop control, especially for pulse-modulated RF signals. In other embodiments, the ALC circuit implements multi-level control for multi-level RF signals. In this manner, the RF generator uses the ALC circuit to generate an RF signal having a constant power level for RF signals having any pulse shape or output levels. In other embodiments, a clock generation circuit in an impedance matching network synchronizes a slave clock to a clock signal of the RF signal when the load impedance is resistive only or when the clock signal of the RF signal has a given phase condition.

Abstract: The present disclosure provides a method and device for processing a video. The method includes: determining a special effect video frame of a video, where a target feature area of the special effect video frame includes a preset special effect map; and modifying a display effect of the special effect map upon determining that a shielded area exists in the target feature area.

Abstract: A method for processing an image, an electronic device and a storage medium are provided. The method includes: obtaining an original image including a target object; obtaining an auxiliary line by extracting semantic information from the original image, the auxiliary line including at least one of: an area boundary line of the target object and a part contour line of the target object; obtaining a prediction result for a semantic line by inputting an image stitched from the auxiliary line and the original image to a predictive neural network, the auxiliary line guiding the predictive neural network to obtain the prediction result, the prediction result indicating a probability that a pixel in the original image is a pixel in the semantic line, the semantic line being used for rendering the target object; and obtaining the semantic line based on the prediction result for the semantic line.
