The embodiment of the invention discloses an image coding method and device, electronic equipment and a computer readable medium. A specific embodiment of the method comprises the steps of obtaining a to-be-processed image; dividing the to-be-processed image to generate at least one prediction block; executing the following processing steps: determining a prediction mode corresponding to the prediction block, representing an intra-frame prediction mode in response to the prediction mode, and determining a reference pixel set corresponding to the prediction block; performing classification processing on each reference pixel in the reference pixel set; determining an available pixel group corresponding to the prediction block; inputting the available reference pixel group, the available pixel group and the unavailable reference pixel group into a pre-trained pixel prediction model to obtain a prediction pixel group corresponding to the unavailable reference pixel group; and performing pixel coding processing on
