Image Processing with java

##About this project The code I was developing on 3-4 years ago, While I studied on Third years in University. My purpose is to use the code in Senior project. Now I don't work in image processing field anymore. I decided to open code for everyone who is interesting in image processing. I want people to lean from my code.

This project develop by using java, image processing concept and basic mathematical formula

#What's inside the project. ###Image2D.java Main class, show example to use function

###Gaussian.java The algorithm for bluring image, I use Gaussian distribution method #####Link

• http://www.pixelstech.net/article/1353768112-Gaussian-Blur-Algorithm
• http://blog.ivank.net/fastest-gaussian-blur.html

###Grayscale.java The algorithm for convert image to gray color, In this file I use Luminosity method, However I can read other method and example at below link #####Link

• http://www.johndcook.com/blog/2009/08/24/algorithms-convert-color-grayscale/

###Histogram.java #####understand about histogram

• http://www.tutorialspoint.com/dip/histograms_introduction.htm
• http://www.tutorialspoint.com/dip/histogram_equalization.htm

#####Math formula

• https://en.wikipedia.org/wiki/Histogram

###Threshold.java The algorithm to convert image to binary color (Separates pixels in an image into a foreground and background) , In this file I use Otsu's method, However you must have understand about histogram first cause by threshold algorithm base on histogram #####understand about Threshold

• https://en.wikipedia.org/wiki/Thresholding_(image_processing)

#####Math formula for Otsu's method

• http://www.ancient-asia-journal.com/articles/10.5334/aa.06113/
• https://en.wikipedia.org/wiki/Otsu%27s_method

###EdgeOperator.java The algorithm to find edge of image , I use Canny Edge algorithm #####Understand about Canny Edge algorithm

• https://en.wikipedia.org/wiki/Canny_edge_detector

#####Definetion and example I follow by this link to implement canny edge and use convolution method to apply value to image

##Read pixel color value ###RGB.java If you get value of pixle from RGB.java to access RGB value on Dicimal digit, You must use bitwise operators to shitf bit. R >> 16 , G >> 8 and B, Then add mask by (& 0xFF), See example in below link or file this project #####link

#Convoluion ##To apply vaule to image, You must have understand Convoluion method
