Reading Image in 1 Dimensional Array

Hello , I'm writing an application and I need to write a method which can read an Image, I found it hard complicated in some times, I wrote a One and I'd like to share it with you
note it is written with Java and it convert gray-scale images to binary 0-1 .

public int [] read_image_in_1d () throws IOException{
// array to be returned
int image_1d []= null ;
// File object to hold the destination
File f = new File("test.jpg");
// buffer for the Image
BufferedImage image = ImageIO.read(f);
// raster to the image
Raster raster = image.getData();
// width
int width = raster.getWidth();
// height
int height = raster.getHeight();
// initialization for the Array
image_1d = new int[width * height];
int k = 0;
//get the image in the array
for(int i = 0 ; i < width ; i++)
for(int j = 0 ; j < height ; j++)
{
int d = raster.getSample(i, j, 0);
// threshold to be adjusted or application dependent
if (d > 127 )
image_1d [k] = 1;
else
image_1d [k] = 0 ;
k++;
}
return image_1d ;
}

I hope it helps you, wish you Good luck in your project .

Designing Entity Relationship Diagram (ERD)

Al Salmo Aliko . Hello, in this post I'll discuss with you how to design good Entity Relationship Diagram ERD . this article for: IT Students learning about database. you are having difficulties in creating ERD. you are developer that need help in database design. let's ask ourselves Why good database design is good ? or why we need ERD? when I started programming Eng / Eman Ahmed was my First teacher, she said you must write your code with pen, and now I told you good database design start with paper and pen or in technological terms start with ERD, ERD is the model which shows logical layout of your database. let's List some advantages of good database design : very low or no redundant data is stored. supporting planed or unplanned queries. good design easy to maintain and modify. from first glance you can understand it. an ERD consist from Entities and relationships between them; there exist...

Sigmoid Function

Hello all, Sigmoid Function or Logistic Function , it is used in Machine Learning problems for the purpose of learning (Neural network ) on curves. its range between ]0,1[ it is horizontal asymptotic on 0 and 1, because of its range between 0 and 1 it is used in classification using threshold for example if we take 0.5 as a threshold values greater than 0.5 are considered Ones and values less than or Equal 0.5 considered 0. it has the following formula : and it shape as following : from wikipedia so it accept differentiation over its domain unlike Step Function. differentiation of sigmoid function : I finished the article , i hope you understand it . Thanks for your time and effort if you like it share and follow me :)
