Behavior feature extraction method, system based on space-time frequency domain hybrid learning, and device

The invention belongs to the field of behavior recognition, particularly relates to a behavior feature extraction method, system based on space-time frequency domain hybrid learning, and a device, andaims to solve the problem of low skeleton behavior feature extraction precision. The method comprises the steps of obtaining a video behavior sequence based on a skeleton, and extracting a time-spacedomain behavior feature map through converting a network; inputting the time-space domain behavior feature map into a frequency domain attention network, performing frequency selection, inverting toa time-space domain, and adding the obtained behavior feature map to the time-space domain behavior feature map; synchronously performing local and non-local reasoning, and performing high-level localreasoning; and globally pooling the time-space domain behavior feature map obtained through reasoning to obtain the behavior feature vector of the video behavior sequence. The method can be applied to behavior classification, behavior detection and the like. According to the method, an effective frequency mode is adaptively selected in a frequency domain, a network with local affinity fields andnon-local affinity fields is adopted in a time-space domain for space-time reasoning, local details and non-local semantic information can be synchronously mined, and therefore the behavior recognition precision is effectively improved.

Picture processing device, picture processing method, and game device and storage medium using the same

The present invention provides a picture processing device capable of realizing the detailed shape and pattern of a display object which is far away from a viewpoint and which attracts a game player's attention. For example, a display object (or player) in a soccer game is composed of a small number of polygons to be displayed on a CRT-type display, etc. when the display object is far away from the viewpoint (or camera position). However, even if the player is at a far position, the player will attract the game player's attention when a ball is passed to the player. If the number of polygons composing the player is small in such a situation, the game player will gain an unnatural impression. For example, assuming that a ball rolls to a certain player and this player obtains priority, a priority mark will be displayed above the player's head. Then, it is determined whether or not the player with the priority mark is close to a certain viewpoint. If the player is close to the viewpoint, no change will be made because the player is already composed of many polygons. On the other hand, if the player is far away from the viewpoint, the number of polygons composing the player will be increased to be almost the same as the number of polygons composing other players located close to the viewpoint.

Multi-resolution LBP textural feature extracting method

The invention discloses a multi-resolution LBP (short for MR-LBR) textural feature extracting method, and belongs to the technical field of image information processing. The method includes the steps that firstly, an input image is preprocessed; secondly, image signals are decomposed and expressed through first-level discrete wavelet transformation, and a high-frequency mean chart is acquired; thirdly, rotation invariant unified LBP calculation is conducted on an original image, a low-frequency approximate subgraph and the high-frequency mean chart, and then an LBP histogram of the original image, an LBP histogram of the low-frequency similar subgraph and an LBP histogram of the high-frequency mean chart are acquired; eventually, the three histograms are spliced into a multi-resolution LBP histogram in a non-overlapping mode for describing texture information of the image. By the application of the method, more textural feature information of the image can be extracted, the defects of existing LBP in the texture processing aspect are overcome, and robustness of extracted features on rotation, illumination and the like is maintained. The multi-resolution LBP textural feature extracting method is applied to classification of fresh green tea leaves, the classification effect is remarkable, and accuracy reaches up to over 92 %.

Image description generation method based on external triple and abstract relationship

The invention discloses an image description generation method based on an external triple and an abstract relation. The method comprises the following steps: firstly, extracting a triple in an image description text, constructing an external relation library, and carrying out feature coding on the triple; and clustering the triples of which the text similarity is higher than a threshold value into one class. Meanwhile, the model performs target detection on the image to obtain a target visual feature set and a target category set; and querying a triple of which the target is similar to the target category in an external relation library according to the text similarity. The model predicts the target, the attribute and the relation of the image by using the visual features of the target to generate a scene graph; and fusing visual features and text features by using a convolutional neural network, and carrying out feature coding on targets, attributes and relationships. And finally, fusing target, attribute and relation coding features of the scene graph and coding features of the similarity relation and the abstract relation, and inputting the fused features into a double-layer LSTM sequence generation model to obtain final image description.
