Abstract: An estimation unit of a visual object tracking apparatus estimates a plurality of estimated bounding boxes and estimated object IDs respectively corresponding to the estimated bounding boxes based on a plurality of predicted bounding boxes and a plurality of detected bounding boxes. For example, the “detected bounding boxes” are “bounding boxes (bounded areas)” detected by a detector in each of a plurality of frames in a time series such as moving images. The “bounding box” is a frame surrounding an image of an object detected in a frame. For example, the “predicted bounding box” is a “bounding box” predicted by a predictor based on an estimated bounding box(es) estimated for one or a plurality of frames in the past.

Abstract: Estimating determines, on the basis of processed quantized values, a quantization interval for quantizing input element values, which are elements of input values serving as a processing object and determines, on the basis of the processed quantized values, a probability distribution of quantization value candidates, which are candidates of quantized values of the input element values; quantizing uses the quantization interval to quantize the input element values and determine a quantized value; and entropy encoding uses the probability distribution to perform entropy encoding of a quantization time sequence which includes quantized value codes indicating the quantized values of the input element values.

Abstract: A monitoring person can rapidly take a countermeasure against a situation occurring in a moving object. Image reception means (31) receives image data obtained by imaging the outside of the moving object. Candidate acquisition means (32) acquires control content candidates of autonomous driving of the moving object. Monitoring screen display means (33) causes a display apparatus to display a monitoring screen. The monitoring screen includes a region where the image data is displayed and a region where the control content candidates are displayed. When one control content is selected from the control content candidates, control content transmission means (34) transmits a control signal representing the selected control content to the moving object.

Abstract: An image reception unit receives an image from a vehicle through a network. An event prediction unit predicts an event based on the image received by the image reception unit. Based on an event result predicted by the event prediction unit an important area identification unit identifies an area related to the predicted event as an important area in the image. An image adjustment unit adjusts image quality concerning the important area, which is identified by the important area identification unit, in the image.
