    摘要： A filtering circuit having the behavior of a low-pass filter capable of having a long time constant. The filtering circuit comprises an input circuit (10) for receiving a voltage input signal to be filtered. A comparator circuit (11) is provided for monitoring the input signal relative to an analog output signal from an accumulator circuit (13) and providing an error signal representative of the difference of the input and output signals. The error signal is fed to a voltage controlled oscillator (17) to generate a frequency signal proportional to the error signal. A frequency dividing circuit (14) is provided to divide the frequency signal by a predetermined division factor to control the low cut-off frequency of the filtering circuit whereby to increase the response time thereof. An accumulator (13) is provided to integrate the frequency signal. An output circuit (33) provides an output of the stored integrated frequency signal to constitute the analog output signal.

    摘要： An image processing method and apparatus are provided. The image processing method includes obtaining a kernel that is deterministically defined based on an extension ratio of a first feature map, up-sampling the first feature map to a second feature map by performing a transposed convolution operation between the first feature map and the kernel, and outputting the second feature map.

    摘要： A method and an apparatus for signal processing: implementing step-by-step orthogonal decomposition of an original signal to be inputted; on the basis of the number of layers of orthogonal decomposition and the edge high frequency bandwidth of the original signal after orthogonal decomposition, generating a finite-length unit impulse response FIR filter; using the FIR filter to filter the edge high-frequency signal of the original signal; and, after passing the signal obtained after filtering and the low frequency signal obtained at each stage of orthogonal decomposition through an orthogonal filter bank, implementing signal synthesis processing.
