“…SCP uses the TCP, similar to the video slice prototype. H.264/AVC is used by Thai et al [ 7 ] and Zhang et al [ 8 ]. Thai et al recorded videos at 25 frames per second (fps) and Zhang et al recorded videos at 30 fps.…”

“…The processing time of one target image transmission was measured in the case of the SCP and the video slice. The image compression by H.264/AVC that simulates Thai et al [ 7 ] and Zhang et al [ 8 ] was not included in this evaluation because H.264/AVC did not work on the Raspberry Pi Zero W as described on Section 5.2 . The time from the beginning to the end of the SCP command was defined as one transmission processing time in the case of SCP.…”

“…The third approach is transmitting the difference data of two images irrespective of whether the images have any differences. Thai et al [ 7 ] and Zhang et al [ 8 ] used a video encoder to generate the difference data of screen images. Thai et al proposed a method that compresses images using a video encoder if the amount of image data does not fit the bandwidth of the network.…”

“…However, it is difficult to identify agricultural images that do not have mechanical changes because the changes in plants are insignificant. The third approach is to use a video encoder to calculate the difference data of two images and then transmit the difference data irrespective of whether the images have differences [ 7 , 8 ]. While these methods can be applied to agricultural monitoring systems, they stack image difference data, making it difficult to restore the subsequent image files transmitted when data are lost by mobile communication disconnection.…”

When agricultural automation systems are required to send cultivation field images to the cloud for field monitoring, pay-as-you-go mobile communication leads to high operation costs. To minimize cost, one can exploit a characteristic of cultivation field images wherein the landscape does not change considerably besides the appearance of the plants. Therefore, this paper presents a method that transmits only the difference data between the past and current images to minimize the amount of transmitted data. This method is easy to implement because the difference data are generated using an existing video encoder. Further, the difference data are generated based on an image at a specific time instead of the images at adjacent times, and thus the subsequent images can be reproduced even if the previous difference data are lost because of unstable mobile communication. A prototype of the proposed method was implemented with a MPEG-4 Visual video encoder. The amount of transmitted and received data on the medium access control layer was decreased to approximately 1/4 of that when using the secure copy protocol. The transmission time for one image was 5.6 s; thus, the proposed method achieved a reasonable processing time and a reduction of transmitted data.
