Summary of image enhance filters (part 2) This filter enhances the contrast between black spots and their surrounding areas. This filter enlarges the remaining black spots so that they are one size larger. This filter leaves only black spots on the target. In the following example, the Real-Time Subtract filter has been combined with the Shrink, Average, and Contrast Conversion filters to produce an almost completely white image with only a black flaw remaining. Several of these filters can be applied at once to the same area to create images that are suitable for external inspection. The CV-X Series includes a variety of pretreatment filters. Let's look at the effects of these filters in detail. In addition to the basic image enhance filters described above, there are other new, advanced image enhance filters such as the subtraction and real-time image extraction filters. The next topic is the image enhance filters (part 2) to modify images to obtain optimum results. You can ensure stable inspection by understanding the principles of individual image enhance filters and using the image enhance filters, solely or in combination, most effective for your application.Typical image enhancement replaces the value of the center pixel in every set of 3 x 3 pixels to a desired enhancement result obtained with various coefficients applied to the density values of the surrounding pixels.If there are features that need enhancement, perform image modification (image enhance filters). First, capture a good source image (clear focus, high contrast).These are the basics of image enhancement.
