Image Filter Tools - Scene Correction

The Scene Correction Image Filter Tool filters a region of the image with a pixel-by-pixel "neighbor" image-enhancement technique called "mean intensity"; outputs a Tool Image that can be referenced by other Location or Inspection Tools.

The "mean intensity" image-enhancement technique filters images based on the pixel intensity of the pixels within the processing neighborhood, which is defined by the Number of Rows and Number of Columns parameters. This filter simulates removing uneven lighting or shading from an image by comparing each pixel's intensity value to the average intensity of the pixels within the processing neighborhood. Areas of the image that show little or no variation will be rendered a neutral grey, regardless of the original intensity. Pixels that are darker than their surrounding pixels will be shaded darker than the neutral grey, according to how much darker they are than their surroundings. Similarly, pixels that are lighter than their surrounding pixels will be shaded lighter than the neutral grey. Edges and sharp transitions will be preserved, similar to a "high-pass" operation.

The Scene Correction Image Filter Tool is useful in application situations where there is uneven lighting or shading in the image.
