Detecting an object in an image using multiband and multidirectional filtering

A detection apparatus, the apparatus comprising:

• processing circuitry configured to perform multiband filtering on a first area to obtain a plurality of band sub-images, the first area being an area in a first video frame;
• perform multidirectional filtering on the plurality of band sub-images to obtain a plurality of direction sub-images;
• acquire a direction-band fused feature of the first area according to the plurality of direction sub-images;
• and
• input the direction-band fused feature into a detection model, and perform detection based on the direction-band fused feature using the detection model to detect whether the first area comprises an object.

A non-transitory computer-readable storage medium storing computer-readable instructions thereon, which, when executed by a computer device, cause the computer device to perform a detection method comprising:

• performing multiband filtering on a first area to obtain a plurality of band sub-images, the first area being an area in a first video frame;
• performing multidirectional filtering on the plurality of band sub-images to obtain a plurality of direction sub-images;
• acquiring a direction-band fused feature of the first area according to the plurality of direction sub-images;
• and
• inputting the direction-band fused feature into a detection model, and performing detection based on the direction-band fused feature using the detection model to detect whether the first area comprises an object.
