作者和其他人提出的最大似然图像恢复的非相干图像以前的研究扩展到考虑盲反卷积的问题，其中系统的脉冲响应被假定为是未知的。激发这项研究的潜在应用是宽视场和共焦荧光显微镜，虽然在天文学和红外成像的应用也被预见。该方法结合了迭代期望最大化算法。虽然精确的脉冲响应被假定为是未知的，但是使用关于脉冲响应的特性的一些先验知识。在所提出的初步仿真研究中，脉冲响应的圆形对称性和带限性质被如此使用。这些模拟展示了这些方法的潜在效用和目前的局限性。
Previous research presented by the author and others into maximum-likelihood image restoration for incoherent imagery is extended to consider problems of blind deconvolution in which the impulse response of the system is assumed to be unknown. Potential applications that motivate this study are wide-field and confocal fluorescence microscopy, although applications in astronomy and infrared imaging are foreseen as well. The methodology incorporates the iterative expectation-maximization algorithm. Although the precise impulse response is assumed to be unknown, some prior knowledge about characteristics of the impulse response is used. In preliminary simulation studies that are presented, the circular symmetry and the band-limited nature of the impulse response are used as such. These simulations demonstrate the potential utility and present limitations of these methods.
