Embodiment approach
[0111] In this embodiment, the server fuses the time-domain audio features and frequency-domain audio features of the multiple audio frames by adding them together to obtain the initial audio features of the target video. The product is used to further integrate the time-domain audio features and frequency-domain audio features, and the obtained audio features can more accurately express the audio characteristics of the target video.
[0112] For example, when the server extracts time-domain audio features through multiple one-dimensional convolution kernels, and extracts frequency-domain audio features through multiple two-dimensional convolution kernels, the dimension of the obtained time-domain audio features is one-dimensional , the dimensionality of frequency-domain audio features is two-dimensional. In this case, the server performs upsampling on the time-domain audio features of the plurality of audio frames to change the one-dimensional time-domain audio features into ...

The invention discloses a background music insertion time point determination method and device, equipment and a storage medium, which can be applied to background music insertion, artificial intelligence, vehicle-mounted scenes and the like in a computer technology. In the embodiment of the invention, the video feature of the target video is determined by combining the audio feature and the image feature of the target video, and the video feature can accurately represent the content of the target video. And coding the video features based on an attention mechanism to obtain a plurality of target parameters. And based on the target parameters of the plurality of time points, determining a candidate time point from the plurality of time points, the candidate time point being a time point at which background music can be inserted in the target video. In the process of determining the candidate time point, the attention mechanism is combined, so that the determined candidate time point is relatively accurate. And meanwhile, when the background music is inserted, the efficiency of inserting the background music into the video is improved on the premise of ensuring the accuracy.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, device and storage medium for determining the insertion time point of background music. Background technique [0002] With the development of Internet technology, watching videos has become a common form of entertainment. In the process of video production, background music is often inserted into the video to enhance the atmosphere of the video through the background music, thereby improving the viewing effect of the video. [0003] In the related art, the insertion time point of the background music is realized by manual selection, that is, in the process of watching the video, the video producer determines the time point of inserting the background music in the video according to the content of the video. [0004] However, the manual selection method consumes a lot of time and human resources, resulting in low efficiency of inserting background mu...
