    摘要: In order to help music players without sufficient musical knowledge to adapt original music pieces but still keep the original style, the present invention provides an interactive system and the accompanying method for creating music by substituting audio tracks. The interactive system includes a database of musical elements that comprises tonality, tempo, beat, timbre, texture, chord, and pitch, a database of music that contains multiple original music pieces, and a processor. As a result, players without strong knowledge in music theories can create adapted a music piece that matches the style of the original one.

    摘要: Method, device, and non-transitory computer-readable medium detecting a gathering of objects based on stereo vision are disclosed, and the method comprises steps of obtaining current and prior images and a corresponding depth map; extracting foreground pixels corresponding to detection objects from the current and prior images, and projecting the foreground pixels onto a ground surface to acquire a foreground projection image including foreground projection blocks; conducting, based on image feature differences of the foreground pixels between the current and prior images, projection onto the ground surface to acquire moving foreground projection blocks; utilizing the moving foreground projection blocks to erode the foreground projection blocks to obtain still foreground projection blocks; and determining, based on the still foreground projection blocks, whether the gathering of objects exists.
