    IPC: G06T7/73

    Abstract: A method for determining a spatial position of an object using an image calibrated relative to a reference frame. The method comprises, after obtaining a candidate region associated with the object in the reference frame and projecting the candidate region into the calibrated image, adjusting the projected candidate region based on an image element associated with the object in the calibrated image, and determining a spatial position of the object using the adjusted projected candidate region.

    Abstract: A method and device for partitioning an image for transmission of one or more regions of interest of said image, the image being composed of coding units, the method comprising: performing a first partitioning of the image into one or more portions of coding units, wherein each portion is encodable or decodable without any coding dependency on another of the portions, a region of interest comprising at least one portion; and performing a second partitioning the image onto one or more segments of coding units comprising at least one independent segment which is encodable or decodable without any coding dependency on another of the segments and at least one dependent segment which is dependent on the independent segment for coding or decoding, the second partitioning being based on the portions of the first partitioning; wherein at least part of one of the portions is encoded in an independent segment and at least part of another of the portions is encoded in a dependent segment.

    Abstract translation: 一种用于分割用于传输所述图像的一个或多个感兴趣区域的图像的方法和装置，所述图像由编码单元组成，所述方法包括：执行图像的第一划分为编码单位的一个或多个部分，其中 每个部分是可编码的或可解码的，而不对另一个部分的任何编码依赖性，包括至少一部分的感兴趣区域; 以及执行将所述图像划分到包括至少一个可编码或可解码的独立片段的编码单元的一个或多个片段上的第二分割，而不对所述片段中的另一片段的任何编码依赖性以及依赖于独立片段的至少一个依赖片段进行编码 或解码，所述第二分区基于所述第一分区的部分; 其中所述部分中的一个的至少一部分被编码在独立的段中，并且所述部分中的另一部分的至少一部分被编码在从属段中。

    Abstract: According to some embodiments, there is provided a Collective Perception Message, CPM, characterizing a plurality of Vulnerable Road Users based on a plurality of received VAMs, thereby allowing an ITS station to efficiently aggregate VAM messages from VRUs and retransmit information about the VRUs to other ITS stations. Consequently, the security is improved as some ITS stations may not be able to detect or identify VRU stations by themselves but thanks to the CPM, these stations can still be informed of the VRUs. According to other aspects, congestion is avoided while maintaining safety vis-à-vis VRUs thanks to the use of a different transmission scheme when the VRU is already characterized in a CPM sent to the ITS stations. Also, a receiving station can evaluate whether the content of a CPM can be trusted or not. Safety is thus improved. This is achieved thanks to the CPM that references a certificate.
