overlayPlot

Overlay two images

Syntax

overlayPlot(bg, fg)
overlayPlot(bg, fg, fg_dnr)
overlayPlot(x, y, bg, fg, fg_dnr)

Description

overlayPlot overlays two 2D images. The background image is displayed using a grayscale map. The foreground is first log-compressed and thresholded to a particular dynamic range, and then overlayed onto the background image using an alpha value of 0.5. If a dynamic range is not specified, a value of 30 dB is used.

Example:

bg = rand(128);
fg = peaks(128);
overlayPlot(bg, fg);

Inputs

x, y

vectors describing the position of the pixels in the image equivalent to image(x, y, c)

bg

background image

fg

foreground image

fg_dbr

dynamic range in dB of foreground image
