LCP-13 Optical Image Differentiation Experiment

Short Description:

Optical differentiation is not only an important optical-mathematical operation, but also an important method of highlighting information in optical image processing. It can well extract and highlight the edges and details of low-contrast images, thereby improving image resolution. Rate and recognition rate. One of the important features of an image is its shape and contour. Under normal circumstances, we only need to identify the contour in the recognition of an image. This experiment introduces the use of optical correlation methods for spatial differentiation of the image, thereby depicting the contour edge of the image. This type of image processing and the use of optical projection type forward projection devices can perform differential correction on images and pictures.
