Packet Compressed Sensing Imaging (PCSI) is digital unconnected image transmission method resilient to packet loss. The goal is to develop a robust image transmission method that is computationally trivial to transmit (e.g., compatible with low-power 8-bit microcontrollers) and well suited for weak signal environments where packets are likely to be lost. In other image transmission techniques, noise and packet loss leads to parts of the image being distorted or missing. In PCSI, every packet contains random pixel information from the entire image, and each additional packet received (in any order) simply enhances image quality. Satisfactory SSTV resolution (320x240 pixel) images can be received in ~1-2 minutes when transmitted at 1200 baud AFSK, which is on par with analog SSTV transmission time. Image transmission and reception can occur simultaneously on a computer, and multiple images can be received from multiple stations simultaneously - allowing for the creation of "image nets." This paper presents a simple computer application for Windows, Mac, and Linux that implements PCSI transmission and reception on any KISS compatible hardware or software modem on any band and digital mode.

数据包压缩传感成像 (PCSI)：通过噪声信道进行稳健的图像传输

数据包压缩传感成像 (PCSI) 是一种数字无连接图像传输方法，可抵御数据包丢失。目标是开发一种健壮的图像传输方法，该方法在传输上的计算量很小（例如，与低功耗 8 位微控制器兼容）并且非常适合可能丢失数据包的弱信号环境。在其他图像传输技术中，噪声和数据包丢失会导致部分图像失真或丢失。在 PCSI 中，每个数据包都包含来自整个图像的随机像素信息，接收到的每个附加数据包（以任何顺序）只会提高图像质量。当以 1200 波特 AFSK 传输时，可以在约 1-2 分钟内接收到令人满意的 SSTV 分辨率（320x240 像素）图像，这与模拟 SSTV 传输时间相当。图像传输和接收可以在计算机上同时进行，并且可以同时从多个站点接收多个图像——从而可以创建“图像网络”。本文介绍了一个适用于 Windows、Mac 和 Linux 的简单计算机应用程序，它可以在任何频段和数字模式下在任何 KISS 兼容硬件或软件调制解调器上实现 PCSI 传输和接收。
