  • Patent number: 11004180
    Abstract: A method for generating dynamic images applied to a computer device includes obtaining a depth image of a static image. A preset region of the depth image is converted into a histogram and an average depth value D is calculated therefrom. A first depth value d1 and a second depth value d2 are determined from the histogram according to the average depth value D. M numbers of third depth values d3 are calculated according to the first depth value d1 and the second depth value d2. Once M number of blurred images are generated according to each M number of third depth values d3, the M number of blurred images are played back according to a magnitude of the third depth value d3 corresponding to each of the M number of blurred images.

  • Patent number: 10964028
    Abstract: A method for dividing an image obtains the image by captured and a depth map of the image. The method creates a histogram of the depth map including horizontal and vertical axes. A clustering algorithm is applied to the data in the histogram to determine upon two data clusters and the cluster centers of the two clusters. The method determines that the abscissa value of the smallest ordinate value between two cluster centers in the histogram is a segmentation threshold. If the obtained segmentation threshold meets a preset condition, the image is segmented into a foreground region and a background region. An electronic device for applying the method is also provided.

  • Patent number: 10896488
    Abstract: A method for removing haze from an image is provided. The image is converted to S(x) and V(x), the S(X) is saturation component of the image, and the V(x) is value component of the image. The S(x) is filtered to obtain S?(x), and the V(x) is filtered to obtain V?(x). A depth d(x) is estimated by calculating a difference between the S?(x) and V?(x). Once a transmission map t(x) is calculated based on the d(x), haze is removed from the image based on the transmission map t(x).
