Abstract: An image encoding method for ensuring quality of an encoded image includes: after obtaining a first image, an encoding device may obtain a first quantization parameter (QP) corresponding to each coding block in at least one coding block in the first image; and then encode each coding block in the at least one coding block based on the first QP corresponding to each coding block, to obtain first image data. The encoding device may determine, based on a quality parameter of each coding block in the first image data, a second QP corresponding to each coding block; and encode each coding block in the at least one coding block based on the second QP corresponding to each coding block, to obtain second image data.

Abstract: The world's cargo is transported in shipping containers. Historically, there has been little visibility into cargo once it goes inside a container. Moisture-sensitive cargo is often damaged in transportation. The present disclosure involves a system for monitoring and predicting water damage in containers. Use of this system can enable pre-emptive action to lessen damage. Specific considerations of container transportation and availability of weather data give this problem unique characteristics, distinguishing it from generic monitoring. These considerations in turn motivate the solution framework presented here.

Abstract: The world's cargo is transported in shipping containers. Historically, there has been little visibility into cargo once it goes inside a container. Breakable cargo, such as glass, is sometimes damaged in shipping. Sensors can be used to measure shocks experienced by the container in transit. The present disclosure presents systems and methods for analyzing such shocks into shock clusters and outliers. The present disclosure also proposes a way to assign probable cause to the shocks in each cluster based on prior knowledge of shock causes. The nature of shock data presents nuances that contribute to the uniqueness of the example implementations herein.

Abstract: The present invention provides a TFT substrate manufacturing method and a TFT substrate. In the TFT substrate manufacturing method of the present invention, a pattern of the gate metal layer has been designed such that reflective blocks are included in a gate metal layer at locations corresponding to areas in which connection holes are to be formed so that in a process of forming the connection holes, light is reflected by the reflective blocks to enhance intensity of exposure on locations where the connection holes are formed. Thus, even under the condition that limit exposure size of an existing exposure machine is constrained, it is still possible to ensure full exposure in forming the connection holes in a high PPI display panel device to thereby realize production of high display panel products.
