In this work, a video communication system to encode river video at a low bit rate is proposed. In the proposed system, a semantic segmantation is performed to organize the coding priority of each segment. Then, by setting an appropriate Quantization Parameter (QP) map for each region with VVenC which is the latest video codec of VVC, a low bitrate coding is achieved. We also compare the encoding performance with the latest Neural Video Codec (NVC), namely, DCVC-DC. The simulation results show that the proposed method with VVenC achieves ultra-low bit coding. Although the current version of DCVC-DC could not achieve ultra-low bit coding, the coding efficiency shows higher performance than that using VVenC in a wide range of bit rate.

In recent applications, a modern object recognition model is available together with the video encoder. In this work, an adaptive bitrate control algorithm is proposed using a You Only Look Once v8 (YOLOv8) model for Versatile Video Coding (VVC). YOLOv8 object detection network, which is also suitable for real-time processing, is used as an algorithm to detect salient regions before encoding. The proposed algorithm estimates Rate-Distortion Cost (RD-Cost) of Coding Tree Units (CTUs) with YOLOv8 and selects the Quantization Parameter (QP) based on the object detection result. Simulation results show that the proposed algorithm achieves a maximum bitrate reduction rate of 7.76% and improves coding efficiency while minimizing image quality degradation.

Unmanned aerial vehicles (UAVs) have remarkably advanced and expected to be useful in a variety of fields. However, there is a serious problem of video quality degradation due to rainy weather, regardless of whether the UAVs are flying autonomously. In this work, we propose a highly accurate method to remove the effect of rain streaks from images captured by UAVs in rainy conditions. This approach uses the multi-axis feature fusion (MFF) block including the kernel basis attention (KBA) module. The proposed method shows better performance than the previous deraining methods in PSNR and SSIM. Moreover, the proposed method is effective for varying rain streak intensity.

In recent years, due to typhoons and torrential rains caused by global warming river overflows have been increasing rapidly. A river monitoring systems using surveillance cameras is considered efficient. However, in mountainous areas the bandwidth is limited that restrict the video transmission with acceptable video quality. In this work, a novel river surveillance system is proposed with a semantic segmentation based important object extraction process followed by a VVC encoder on the river side which only encode the context of the most important objects to save encoding bits. On the other hand, unimportant context is generated on the decoder side in the server side with a VQGAN model. The simulation results show that the proposed system can not only significantly reduce the bitrate but also keep a very high subjective video quality.

A sugarcane yield of one plantation area depends on several independent variables. Practically it is challenging to predict accurately by using conventional methods. This study aims to develop a decision model based on a combination of fuzzy logic and object-oriented methods to predict sugarcane yield. The research is conducted in four main stages, employing object-oriented methods for model design and fuzzy logic for model construction. Object and activity diagrams are used for the object-oriented model design. The fuzzy membership functions employed are a combination of trapezoidal and triangular shapes. The resulting decision model can simulate 2,225 data from plantation areas in Indonesia. Based on the 10 examples of plantation area data in Indonesia, plantation number one obtained the largest sugarcane yield, which was 4.79%, with a similarity value of 0.90 (when compared to manual calculations as its ground truth). This similarity value is a higher value when compared to the average similarity value, which is 0.89.
