1. An image transmission system comprising:
- a transmission device comprising;
one or more first processors, andat least one first memory coupled to the one or more first processors, the at least one first memory having instructions stored thereon which, when executed by the one or more first processors, cause the transmission device to;
divide image data into a plurality of regions on the basis of a similarity of pixels, andtransmit the image data and region representative points of the plurality of regions; and
a reception device comprising;
one or more second processors, andat least one second memory coupled to the one or more second processors, the at least one second memory having instructions stored thereon which, when executed by the one or more second processors, cause the reception device to;
receive the image data and the region representative points transmitted from the transmission device,assign, for each pixel in the image data, one of the region representative points based on distances between respective region representative points and the pixel in a feature space,update a location and a pixel value of the region representative point in the image data on the basis of locations and pixel values of pixels assigned to the region representative point, andgenerate region labels used for identifying the plurality of regions, using the image data and the region representative points whose location and pixel value have been updated.

Abstract
A transmission device divides image data into a plurality of regions on the basis of a similarity of pixels and transmits the image data and region representative points of the plurality of regions. A reception device receives the image data and the region representative points transmitted from the transmission device. The reception device generates region labels used for identifying the plurality of regions using the image data and the region representative points.

6. An image transmission system comprising:
-
a transmission device comprising; one or more first processors; and at least one first memory coupled to the one or more first processors, the at least one first memory having instructions stored thereon which, when executed by the one or more first processors, cause the transmission device to; divide image data into a plurality of regions on the basis of a similarity of pixels, transmit the image data and region representative points of the plurality of regions, compress image data, and transmit the compressed image data and region representative points calculated using the image data before compression; and a reception device comprising; one or more second processors; and at least one second memory coupled to the one or more second processors, the at least one second memory having instructions stored thereon which, when executed by the one or more second processors, cause the reception device to; receive the transmitted image data and the region representative points, decompress the compressed image data, and generate region labels used for identifying the plurality of regions, using the decompressed image data and the transmitted region representative points.

7. A control method of an image transmission system having a transmission device and a reception device, the control method comprising:
-
dividing, at the transmission device, image data into a plurality of regions on the basis of a similarity of pixels; transmitting, from the transmission device, the image data and region representative points of the plurality of regions; receiving, at the reception device, the image data and the region representative points transmitted from the transmission device; assigning, for each pixel in the image data, one of the region representative points based on distances between respective region representative points and the pixel in a feature space; updating a location and a pixel value of the region representative point in the image data on the basis of locations and pixel values of pixels assigned to the region representative point; and generating, at the reception device, region labels used for identifying the plurality of regions using the image data and the region representative points whose location and pixel value have been updated.
