    摘要: An imaging control apparatus is configured to detect a first object and a second object appearing on an image captured by a camera. The first object is higher in luminance than the second object. When the second object is not detected on the image, the imaging control apparatus works to adjusts an exposure time of the camera to a first exposure time which is used when the first object is detected. Alternatively. When the second object is detected, the imaging control apparatus adjusts the exposure time of the camera to a second exposure time which is longer than the first exposure time. This eliminates a failure in identifying colors on the image and also minimizes a risk of appearance of flicker on the image.

    摘要: A computer-implemented method for training a birds-eye-view (BEV) object detection model includes inputting a training sample into the model. The training sample includes a BEV image with multiple pixels, and multiple target confidence values. Each pixel of the pixels is associated with a target confidence value of the target confidence values. The method includes receiving as output from the model multiple predicted confidence values. Each predicted confidence value is associated with a pixel of the pixels. The method includes adjusting a parameter set of the model according to a loss. The loss is based on the predicted confidence values and the target confidence values.

    摘要: A subject detection method is disclosed. A moving object is detected on an image to obtain a moving object region, candidate regions are obtained by sliding a sliding box on the image, a first region is determined. The first region is one of candidate regions and contains a part of the moving object region with a largest area. A proportion of the first region is obtained, a size of the first region is adjusted based on the proportion to obtain a second region, a proportion of the second region is obtained. The first region is replaced with the second region, the proportion of the first region is replaced with the proportion of the second region, and it is returned to adjusting the size of the first region until a number of iterative adjustments reaches a threshold, a region obtained by the last adjustment is determined as a target region.

    摘要: A bullet-screen comment display method is provided. The method includes: detecting a target object in an original frame image of a video at a first preset frequency in a process of playing the video, and when the target object is detected, outputting a display area of the target object in the original frame image; generating a mask image corresponding to the original frame image based on the display area, obtaining a bullet-screen comment display area corresponding to the original frame image; and if there is an overlapping area between the bullet-screen comment display area and the display area of the target object in the original frame image, combining the mask image and a bullet-screen comment displayed in the bullet-screen comment display area into a video picture with a non-obstructive bullet-screen comment, and displaying the video picture with a non-obstructive bullet-screen comment at a bullet-screen comment layer, where a bullet-screen comment included in the video picture with a non-obstructive bullet-screen comment does not block the target object.
