hi im getting error all

Not able to fetch and get the output

I am getting the result but i am getting blank images can you help me with it.

Accuracy

Do you have any code to find the accuracy ?. It would be helpful if you provide any code.

What to do next after creating a virtual env. & installing packages from requirement.txt?

I am pretty new to the python world & I have been able to successfully create virtual environment & installing packages from requirement.txt. But I can't figure out what to do next to run your code. Please help me out with the situation. I couldn't understand from the "Example".

Example Code Not Working

The current example code in the readme (directories, filename, ...) does not match detect.py input. Would be nice to have a command line "python3 detect image.jpg" example.

Should have unit testing

The project should have unit testing. Currently the testing is only held by manually running the example script.

Error on use

Installing and using pimage like so:

from pimage import copy_move

copy_move.detect("dataset_example_blur.png", "output", verbose=True)

Will result in error:

help about output

hi,I used your example diagram for testing, but I copied and pasted it myself, again with blank results.
The way I do it is just regular copy and paste.
I wonder why?
Thank you very much!

quadratic speed up

So the loop in ImageObject.analyze

        for i in tqdm(range(featureContainerLength)):
            for j in range(i + 1, featureContainerLength):

can be changed to

        for i in tqdm(range(featureContainerLength-1)):
            j = i+1

giving a speedup of a factor >1000 on the analyze step (depending on image dimensions).
That step on the test image goes from 384 to 0.11 seconds on my PC.

This can be done because the feature list is already sorted, so you don't have to compare each block to every other block. You only need to compare it to the next block.

The original paper clearly states this:

identical blocks correspond to adjacent pairs in the sorted list

"resource/empty.png" is missing

When I run main_GUI.py I get an error:

Traceback (most recent call last):
  File "main_GUI.py", line 123, in <module>
    app = aFrame(root)
  File "main_GUI.py", line 23, in __init__

    fp = builtins.open(filename, "rb")
IOError: [Errno 2] **No such file or directory: 'resource/empty.png'**

Error when computing c4_part1

Hi - I am trying to run the code over the horse_fake.png example, but I have reduced the blocksize to decrease the runtime, with the following problem on macOS:

Traceback (most recent call last):
File "main.py", line 10, in
forgery_detect.detect('../test_images/', image_file, '../output_images/', blockSize=8) # was 32
File "/Users/j/src/Image-Forgery-Detection/forgery_detect/forgery_detect.py", line 22, in detect
imageResultPath = singleImage.run()
File "/Users/j/src/Image-Forgery-Detection/forgery_detect/image_object.py", line 82, in run
self.compute()
File "/Users/j/src/Image-Forgery-Detection/forgery_detect/image_object.py", line 127, in compute
self.featuresContainer.addBlock(imageBlock.computeBlock())
File "/Users/j/src/Image-Forgery-Detection/forgery_detect/Blocks.py", line 38, in computeBlock
blockDataList.append(self.computeCharaFeatures(4))
File "/Users/j/src/Image-Forgery-Detection/forgery_detect/Blocks.py", line 118, in computeCharaFeatures
c4_part1 += self.imageGrayscalePixels[xCoordinate, yCoordinate]
TypeError: unsupported operand type(s) for +=: 'int' and 'tuple'

Any ideas?

Thanks!

Implementation of GUI for Py 3.x

Im trying to implement the GUI for the new repo with the help of your old repo, but im getting an error. Below is the error what im getting now. can you please help me fix it. And ill attach the GUI code and the detect.py code to this.

Exception in Tkinter callback

TypeError: detect() got multiple values for argument 'block_size'

Confusion Matrix

This would be the last help i would ask from you. Thank you so much for all the help you have done. I tried different codes for confusion matrix and none of them worked for me. I just need the code for confusion matrix .So could you please help me with this. And i would be really greatfull for all your help.
