A relay device may receive first information and second information from the image processing device. The relay device may select one of a first processing and a second processing based on at least one of the received first information and the received second information. The relay device may send, to an image processing device, first instruction information causing the image processing device to execute the first processing when the first processing is selected. The relay device may send, to the image processing device, second instruction information causing the image processing device to execute the second processing when the second processing is selected. The relay device may receive the first image data according to the first instruction information or the second instruction information. The relay device may generate second image data by executing the selected image processing on the first image data that has been received.

An example embodiment may involve obtaining an ab pixel macro-cell from an input image. The ab pixel macro-cell may contain 4 non-overlapping mn pixel cells. The ab pixels in the ab pixel macro-cell may have respective color values and may be associated with respective object type tags. The example embodiment may also include selecting a compression technique to either (i) compress the ab pixel macro-cell as a whole, or (ii) compress the ab pixel macro-cell by compressing each of the 4 non-overlapping mn pixel cells separately. The example embodiment may further include compressing the ab pixel macro-cell according to the selected compression technique, and writing a representation of the compressed ab pixel macro-cell to a computer-readable output medium.

According to embodiments illustrated herein there is provided a method of image compression. The method includes generating a modified image based on a compression of an image. The method further includes generating a first residual layer and a second residual layer based on a comparison of the modified image and the image. The method further includes filtering a set of pixels from the first residual layer and the second residual layer. The method further includes compressing the filtered first residual layer and the filtered second residual layer to generate a compressed first residual layer and a compressed second residual layer. Additionally, the method includes generating a second compressed image based on the modified image, the compressed first residual image and the compressed second residual image.
