Objective. This work described a video information processing scheme for optogenetic forms of visual cortical prosthetics. Approach. The architecture is designed to perform a processing sequence: Initially simplifying the scene, followed by a pragmatic visual encoding scheme which assumes that initially optical stimulation will be stimulating bulk neural tissue rather than driving individual phosphenes. We demonstrate an optical encoder, combined with what we called a zero-run length encoding (zRLE) video compression and decompression scheme—to wirelessly transfer information to an implantable unit in an efficient manner. In the final step, we have incorporated an even power distribution driver to prevent excessive power fluctuations in the optogenetic driving. Significance. The key novelty in this work centres on the completeness of the scheme, the new zRLE compression algorithm and our even power distributor. Main results. Furthermore, although the...

植入式光遗传学视觉假体的可扩展数据传输方案

客观的。这项工作描述了视觉皮层假体的光遗传学形式的视频信息处理方案。方法。该架构旨在执行一个处理序列：最初是简化场景，然后是实用的视觉编码方案，该方案假设最初的光学刺激将刺激大量神经组织，而不是驱动单个光幻视。我们展示了一种光学编码器，结合我们所谓的零运行长度编码 (zRLE) 视频压缩和解压缩方案——以有效的方式将信息无线传输到可植入单元。在最后一步中，我们加入了一个均匀的功率分配驱动器，以防止光基因驱动中的功率波动过大。意义。这项工作的关键新颖之处在于方案的完整性，新的 zRLE 压缩算法和我们的均匀功率分配器。主要结果。此外，虽然...
