Embodiment Construction
[0046] The present invention will be described in detail below in conjunction with specific embodiments.
[0047] Such as figure 1 As shown, the video shot boundary detection method of the present invention comprises the following steps:
[0048] 1) Read the video sequence M to obtain the RGB information matrix of each frame of image. Since the HSV color model is more intuitive and more in line with the visual experience of the human eye, the HSV color information matrix of the image frame is obtained through the following conversion formula:
[0049]
[0050]
[0051]
[0052] Among them, R, G, and B respectively represent the red, green, and blue color components of the image pixel, and H, S, and V represent the hue, saturation, and brightness component values of the HSV color space, and the value range is [0,1] .
[0053] 2) Data quantization and compression. Multimedia video data is famous for its huge amount of data. In the process of analyzing video data...
