  • Publication number: 20240193723
    Abstract: The invention provides a channel attention (CA)-based Swin-Transformer image denoising method and system. A noisy image is inputted into a trained and optimized denoising network model. A shallow layer feature extraction network in the denoising network model first extracts shallow layer feature information such as noise and channels in the noisy image. The extracted shallow layer feature information is then inputted into a deep layer feature extraction network in the denoising network model to acquire deep layer feature information. Subsequently, the shallow layer feature information and the deep layer feature information are inputted into a reconstruction network of the denoising network model to perform feature fusion, so that a clear image can be obtained, thereby overcoming problems that an image denoising method based on a deep convolutional neural network is prone to a loss of details in an inputted noisy image and high computing memory and time consumption.

  • Patent number: 9742382
    Abstract: A flip-flop circuit may include a first latch and a second latch. The first latch, which may operate as a “master” latch, includes a first input terminal to receive a data signal, a second input terminal to receive a clock signal, and an output terminal. The second latch, which may operate as a “slave” latch, includes a first input terminal connected directly to the output terminal of the first latch, a second input terminal to receive the clock signal, and an output terminal to provide an output signal. The first latch and the second latch are to be clocked on the same phase of the clock signal, thereby eliminating the need to include clock inversion circuits that generate complementary clock signals.

  • Patent number: 9350325
    Abstract: A CMOS D-type flip flop (D-FF) exhibits reduced power consumption by selectively disabling certain charging/discharging operations at specific circuit elements to minimize the capacitance of the circuit's internal nodes using a partial signaling technique. A clock inverter module may be used to provide a partial inverse clock signal that is the complement of a clock signal when a non-clock dependent input to the clock inverter module has a first value and to provide a fixed signal when the non-clock dependent signal has a second value. One or more MOSFETs controlled by the partial inverse clock signal do not charge or discharge when the non-clock dependent signal has the second value.

  • Publication number: 20120272302
    Abstract: Techniques for generating a human user test for online applications or services may include splitting the visual objects in an image into multiple partial images, and forming one or more alignment positions. At each of the alignment positions, some of the visual objects appear recognizable while some bogus visual objects also appear to prevent robots from recognizing the alignment positions. A user is requested to find the multiple alignment positions to return recognizable visual objects. A system determines that the user is a human user if the recognizable visual objects input by the user match the visual objects in the image.
