A morphological optoelectronic image processor based on the threshold decomposition concept is described and demonstrated. Binary slices of a gray-scale input image are optically convolved with a binary structuring element of arbitrary size and shape in a noncoherent convolver. The slices are displayed on a liquid-crystal spatial light modulator of 320 x 264 pixels. The kernels are implemented as modifications of the system impulse response. The processor's convolution patterns are recorded with a CCD camera and fed into a PC by a frame grabber. Subsequent elementary morphological operations are looped. Examples of processing an input image of 256 x 256 pixels and 16 gray levels with kernels of arbitrary size are presented.
描述并演示了一种基于阈值分解概念的形态学光电图像处理器。灰度输入图像的二进制切片在非相干卷积器中与任意大小和形状的二进制结构元素进行光学卷积。这些切片显示在一个320×264像素的液晶空间光调制器上。内核通过修改系统脉冲响应来实现。处理器的卷积模式由电荷耦合器件（CCD）相机记录，并通过帧捕捉器输入到个人计算机（PC）中。随后对基本形态学操作进行循环处理。给出了使用任意大小内核处理256×256像素、16个灰度级的输入图像的示例。
