How To Read an Image and convert to EmguCV Type?

April 7, 2013

Here's how to read an image file from your hard drive and use it as EmguCV type color image in your code?
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:

@"E:\IMAGES\BirthdayCard.jpg"


NOTE:

Level 4c Part III - How to Collect face images for Training Set and Ensure Improved Recognition

March 9, 2013

Problem:
Are you about to collect face images for your training set(faces database)?
OR
you already did BUT your recognition results are NOT so good?

Solution: Then this video tutorial is especially for you! 
Face Recognition results HIGHLY depend on the faces you store in the training Set vs. the face you try to recognize. YOUR task is to ENSURE that your training set(faces database) is WELL made!
"well made"? just watch video 1 and you'll know what things to be careful of when creating your Training Set!

Solution for NullReferenceException

February 28, 2013

So, i checked the comments many readers posted and 've been getting this complaint  A LOT from MANY users, where most say something like this:

"I am having a NullRefrenceException error during runtime and the block of code it point to is below:

var faces =
grayframe.DetectHaarCascade(haar, 1.4, 4,
HAAR_DETECTION_TYPE.DO_CANNY_PRUNING,
new Size(25, 25))[0]; "

Part of the solution to a problem is understanding what the problem is.

Level 0-EmguCV Installation Guide for 64-bit Windows users

February 27, 2013

LEARNING OBJECTIVE:


There are two options available, but the basic steps are same.
The 2 options  are summarized as below:

METHOD 1: Install the 32-bit version EmguCV on your 64-bit system – yes its possible AND more rewarding than method 2  ^_^
Benefits?

  1. Allows you to avoid the of 64-bit and 32-bit compatibility issues while following my code!
  2. Allows you to use MS Access database in your EmguCV project as well.

Drawbacks?
i haven't noticed any.yet.

METHOD 2: Install the 64-bit version EmguCV on your 64-bit system – what everyone usually does.
Benefits?

  1. ummm...it works perfectly well?…

Level 3e - How to Extract the Detected Faces From Input Image

April 30, 2012

LEARNING OBJECTIVE:
Once faces have been detected from an input image, extract each single face out and save to a folder OR view on the windows form in a picturebox

NOTE: we're starting off with modifying the Camera Capture application, right where we left it at the end of Level 3d. how we connected to camera, got an input image, detected faces and marked them in boxes and displayed them - to know all that, please have a detailed look at Level 1 and then  Level 3a to Level 3d

STEP 1:  If you still haven't then Add a button to "Browse For Input Image" on your application.

STEP 2:  Insert the Co…

Level 4b - PART I - Learn What 'PCA EigenFaces' Method is And What It Does

February 9, 2012

LEARNING OBJECTIVES of Part I (left) and Part II(right):

 
In Level 4a,we learned what is...
--face recognition, why use it?
--difference in recognition and detection?
--existing approaches of face recognition?
--why Select PCA EigenFaces method for face recognition?
--Brief introduction to PCA Eigenfaces

We now continue our series with understanding the concepts of PCA eigenface. i have made this tutorial as a narrated, animated video presentations, covering all the content  - in an attempt to make "theory"  simple, short, demonstrative AND a bit LESS boring :P
