IM (version 1.0)

displayImg: Display an image in grayscale

Description

Display an image in grayscale. If the image is in color, it will still be displayed in grayscale. All images displayed will be processed with histogram equalization.

Usage

displayImg(img)

Arguments

img

A matrix or numeric array representation of the image. If the image is not in grayscale, it will still be displayed in grayscale. If using a CmplxIm, Image, or OrthIm object, the original image would be represented as obj@I and the reconstructed image would be obj@reconstruction. For MultiIm object, function takes in list of images. In this case the input argument would be obj@imageList to access the original images or obj@reconstructionto access the reconstructed images. If the input is a list of images, they will all be plotted in one window.

Examples

#### display the original image in a "OrthIm" object.
data(pirate);

#create OrthIm object from image
obj <- new("OrthIm",img = img,filename = "");
momentType(obj) = "cheby";
setOrder(obj) = c(200,200);

#display original image
displayImg(obj@I);
