  • Learning singing from speech
    Patent number: 11430431
    Abstract: A method, computer program, and computer system is provided for converting a singing voice of a first person associated with a first speaker to a singing voice of a second person using a speaking voice of the second person associated with a second speaker. A context associated with one or more phonemes corresponding to the singing voice of a first person is encoded, and the one or more phonemes are aligned to one or more target acoustic frames based on the encoded context. One or more mel-spectrogram features are recursively generated from the aligned phonemes, the target acoustic frames, and a sample of the speaking voice of the second person. A sample corresponding to the singing voice of a first person is converted to a sample corresponding to the second singing voice using the generated mel-spectrogram features.

  • Image retrieving apparatus having image flicker detection mechanism and image flicker detection method of the same
    Publication number: 20220191382
    Abstract: The present disclosure discloses an image flicker detection method that includes the steps outlined below. An image retrieving is performed to retrieve a current image. A current variation ratio between first rows of pixels of the current image and second rows of pixels in a previous image is calculated. When both the current variation ratio and a previous variation ratio are determined to be larger than a ratio threshold, a detected flicker number is incremented. When the detected flicker number is determined to be larger than a flicker number threshold, a flicker condition is determined to occur. When the detected flicker number is determined to be not larger than the flicker number threshold, the current image becomes the previous image and the current variation ratio becomes the previous variation ratio such that a next image becomes the current image to repeat the above steps.

  • METHOD AND CIRCUIT SYSTEM FOR COMPRESSING VIDEO SIGNALS BASED ON ADAPTIVE COMPRESSION RATE
    Publication number: 20220191507
    Abstract: A method for compressing video signals based on adaptive compression rate and a circuit system thereof are provided. In the method, a digital signal processor is used to process a video so as to frame-by-frame obtain statistical data, for example, a maximum of compressed data. The maximum of compressed data of a previous frame is used to determine a compression state of a current frame. The compression state of the frame allows the processor to decide a direction to adjust a compression ratio. Next, statistical data of the previous frame is used to decide a stride to adjust the compression ratio. The statistical data can be a maximum of compressed data and a quantization table scale referred to rendering a prediction curve that allows the processor to determine the stride. A compression ratio is then determined according to the direction and the stride of adjustment.
