The invention discloses an image frame transmission method, image frame coding equipment, image frame decoding equipment and a medium, relates to the technical field of augmented reality, and discloses the image frame transmission method applied to a coding side, the method comprises the following steps: obtaining coding data of a to-be-transmitted image frame, and determining the data length of the coding data; if the data length is greater than a preset length, performing subpackaging processing on the coded data based on a balanced subpackaging strategy to generate at least two sub-coded data; taking the sub-coded data, the fragment number corresponding to the sub-coded data and the image frame number of the to-be-transmitted image frame as data segments of a data packet; and sending the data packet to a decoding side. On the basis, effective subpackage processing can be carried out on the basis of the to-be-transmitted coded data, meanwhile, after subpackage, auxiliary subpackage information such as a fragment number and an image frame number is added into a data segment, stable subpackage processing is achieved through the auxiliary subpackage information, and the conditions of delay and frame drop of played content are avoided.

The invention relates to an image processing method and device, electronic equipment and a medium. The image processing method comprises the steps that the outer contour of a target body in a to-be-processed first image is expanded outwards and contracted inwards to obtain a second image, and the first image is composed of the target body and a background image; according to the first image, pixels are filled in a first area between external expansion and internal contraction of the outer contour in the second image and fused in the first image, a third image is obtained, and the pixels filled in the first area are related to the background image; performing fuzzy processing on the third image to obtain a fourth image; and fusing the target main body in the first image with the fourth image to obtain a target image. According to the image processing method and device, the first area possibly generating smear is determined, the pixels related to the background image are filled, smear cannot occur between the target body and the background image after the background image is subjected to fuzzy processing, and therefore the image processing effect is improved.
