Abstract The visual perception mechanism of marine cephalopods such as octopus, with respect to “color blind camouflage” has not yet been revealed. The eyeball optics of these animals have longitudinal chromatic aberration, which result in blurred retinal image. Utilizing deconvolution image processing method to restore the chromatic blurred retinal images is proposed in order to obtain the ideal spectral images, which realizes spectral and spatial resolution. Simulation of a target for validating image restoration is implemented, and the results show that the method can effectively extract spectral images from the chromatic blur images. Although the vision of these animals is unlikely to have a cognitive function similar to image deconvolution, the proposed method may provide a technical approach for constructing novel bionic hyperspectral imaging systems.

色盲动物视网膜彩色模糊图像的光谱鉴别和空间分辨率

摘要 章鱼等海洋头足类动物对“色盲伪装”的视觉感知机制尚未阐明。这些动物的眼球光学具有纵向色差，导致视网膜图像模糊。提出了利用反卷积图像处理方法来恢复彩色模糊的视网膜图像，以获得理想的光谱图像，实现光谱和空间分辨率。对用于验证图像恢复的目标进行仿真，结果表明该方法可以有效地从彩色模糊图像中提取光谱图像。虽然这些动物的视觉不太可能具有类似于图像去卷积的认知功能，
