[0024] Example 1
[0025] See figure 1 An embodiment of the present invention provides a method for reconstructing an image, the method including:
[0026] 101: Obtain predicted image data, and output predicted image data in a preset direction;
[0027] 102: Obtain residual image data, and output the residual image data in a preset direction;
[0028] 103: Each time a preset direction predictive image data and a preset direction residual image data are output, a preset direction predictive image data and a preset direction residual image data are added, and output preset by preset direction Add the directions to get the reconstructed image.
[0029] It should be noted that step 101 and step 102 are executed in parallel.
[0030] Specifically, when the preset direction is a column, the method is specifically:
[0031] Obtain predicted image data, and output predicted image data in columns;
[0032] Obtain residual image data, and output residual image data in columns;
[0033] Each time a c...

[0055] Example 2
[0056] See figure 2 An embodiment of the present invention provides a method for reconstructing an image, the method including:
[0057] 201: Read the reference image data A in the decoded signal by column, perform image prediction on each column of reference image data A according to the prediction information in the decoded signal to obtain predicted image data B, and output the predicted image data B by column.
[0058] Assuming that the reference image data A has a size of N×N, taking N=4 as an example, the reference image data A can be expressed as:
[0059] A = a 00 a 01 a 02 a 03 a 10 a 11 a 12 a 13 a 20 a twenty one a twenty two a twenty three a 30 a 31 a 32 a 33
[0060] Where a ij (i∈[0,3], j∈[0,3]) represent the elements of reference image data A, read reference image data A in columns, that is, read a in seq...

[0080] Example 3
[0081] See image 3 An embodiment of the present invention provides a method for reconstructing an image, the method including:
[0082] 301: Read the reference image data A in the decoded signal by line, perform image prediction on each line of the reference image data A according to the prediction information in the decoded signal to obtain predicted image data B, and output the predicted image data B by line.
[0083] Assuming that the reference image data A has a size of N×N, taking N=4 as an example, the reference image data A can be expressed as:
[0084] A = a 00 a 01 a 02 a 03 a 10 a 11 a 12 a 13 a 20 a twenty one a twenty two a twenty three a 30 a 31 a 32 a 33
[0085] Read reference image data A in rows, that is, read a in sequence 00 , A 01 , A 02 , A 03 , A 10 , A 11 , A 12 , A 13 , A 20 , A 21 , A 22 , A 23 , ...
