Here's how to read an image file from your hard drive and use it as EmguCV type color image in your code?
Image<bgr, byte> EmguImage = new Image<bgr, byte>(new Bitmap(@"E:\IMAGES\BirthdayCard.jpg"));
Description: We declared a new variable of type EmguCV color image. We called this variable 'EmguImage'. we initialized it(assigned value to it) to an image named ‘BirthdayCard’ with .jpg extension – remember to ALWAYS add extension of file!
This BirthdayCard.jpg is stored at location ‘E:\IMAGES\’ so the complete path of image becomes:
NOTE: We added the ‘@’ sign before the path to allow single back-slash (\) to be read as a single back -slash as in a path. If you remove ‘@’ sign, then make sure you add one more back-slash to each existing one, like this: "E:\\IMAGES\\BirthdayCard.jpg"
