Image recognition method and device, and image presentation time adjustment method and device

An image recognition device, comprising:

• a processor;
• a memory;
• and
• an interface circuit, wherein the memory, the interface circuit and the processor are interconnected, wherein the memory stores program instructions, which, when executed by the processor, cause the processor to:
• set a presentation time sequence corresponding to an image sequence, wherein the image sequence comprises N images, N is a positive integer, the presentation time sequence comprises a presentation time of each image in the image sequence, a presentation time of an image i is used to indicate a time period from a presentation start moment of the image i to a presentation start moment of a next adjacent image, the image i is any image in the image sequence, the presentation time sequence comprises at least two unequal presentation times, a difference between any two presentation times of the at least two unequal presentation times is k×Δ, k is a positive integer, and Δ is a preset time period value,
• process the image sequence by using a computer vision algorithm, to obtain a computer vision signal corresponding to each image in the image sequence,
• cause the interface circuit to obtain a feedback signal that is generated when an observation object watches the image sequence displayed in the presentation time sequence and that corresponds to each image in the image sequence, wherein the feedback signal is used to indicate a reaction of the observation object to the watched image, and
• fuse, for each image in the image sequence, a corresponding computer vision signal and a corresponding feedback signal to obtain a target recognition signal of each image in the image sequence, wherein the target recognition signal is used for image recognition.

A computer readable storage medium, wherein the storage medium is configured to store program instructions, which, when executed by a processor, cause the processor to perform the operations of recognizing a brain-computer combination image based on image sequence presentation, the operations comprising:

• setting a presentation time sequence corresponding to an image sequence, wherein the image sequence comprises N images, N is a positive integer, the presentation time sequence comprises a presentation time of each image in the image sequence, a presentation time of an image i is used to indicate a time period from a presentation start moment of the image i to a presentation start moment of a next adjacent image, the image i is any image in the image sequence, the presentation time sequence comprises at least two unequal presentation times, a difference between any two presentation times of the at least two unequal presentation times is k×Δ, k is a positive integer, and Δ is a preset time period value;
