thank you. i will try that. i need the binary value for my own neural network text recognition input.

sorry for the lack of details. i actually need to convert the threshold image as a binary value and save it to a text file

i did this:

Imgproc.threshold(picture1, picture2, 127, 1, THRESH_BINARY);

but then how do i save the text file?

What do you mean? does it directly threshold it to binary?

I have a 19x19 image which have already been thresholded. now i need to read every pixel and determine if its black than output it as 1, if its white than output it as 0. please help ASAP. any help would be much appreciate.

Edited:

I need to output the binary to a text file

How do i resize an image in opencv4android. please help. this is my code

public void onManagerConnected(int status) { 
switch (status) { 
case LoaderCallbackInterface.SUCCESS: 
{ 

/* Now enable camera view to start receiving frames */ 
File pictureFile = getOutputMediaFile(); 
img = Highgui.imread(pictureFile.getAbsolutePa... 

roi = new Rect(0, 0, 1920, 1920); 
cropped = new Mat(img, roi); 

Highgui.imwrite(pictureFile.getAbsolut... cropped); 

(Toast.makeText(getApplicationContext(... "Process Done !", Toast.LENGTH_LONG)).show(); 

} break; 
default: 
{ 
super.onManagerConnected(status); 
} break; 
} 
} 
};

As you see in the code, i already cropped the image. It produce a 1920x1920 image. Please give me the exact coding to resize the produced image to 171x171
