Convert the image to grayscale (black and white). Because astronomy images are in grayscale, and because grayscale is a little easier to understand, let’s convert your color image to grayscale. In the ImageJ menus, go to “Image” “Type” “8-bit.” Voila! Your image is in grayscale.

2. Conversion to grayscale. In the grayscale —in a black-and-white picture— there is no color, just different shades of gray. As you will see (literally), we can simulate a grayscale in the RGB color system by making the red, green, and blue components the same —changing them to what is called the pixels luminancy value.

1.1.1 RGB Color Model . The RGB (Red, Green, Blue) color model is an especially important one in digital image processing because it is used by most digital imaging devices (e.g., monitors and color cameras). In the RGB model, a color is expressed in terms that define the amounts of Red, Green and Blue light it contains. Figure 1: RGB Color ...

RGB to HSI conversion. Warning Maths ahead (, (but don't worry). We have now discussed two colour models and need to consider how to convert from one to another. Normalisation. To convert RGB to HSI, we first need to normalise: For many applications, we need to be able to map (or scale) our colour values onto whatever space is available.

The number of bytes is the size of an RGB_8 times the width times the height of the image.Next, modify your main() to read the image. Before you call your PPM_read_header() function, you will need to allocate an array to hold the image. To do so, declare a pointer to an RGB_8, and use the new operator to allocate it, like so:

The luminance provides a grayscale version of the image (such as the image on a monochrome receiver), and the chrominance components provide the extra information that converts the grayscale image to a color image. Luminance-chrominance representations are particularly important for good image compression.
