kandi X-RAY | bpcs Summary

bpcs is a Python library typically used in Telecommunications, Media, Media, Entertainment, Artificial Intelligence, Computer Vision applications. bpcs has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. However bpcs has 2 bugs. You can download it from GitHub.

The goal of steganography is to hide a message in plain sight. BPCS is a method to embed a message in an image by replacing all "complex" blocks of pixels in the image with portions of our message. It turns out that portions of the image with high complexity can be entirely removed (or in this case, replaced with our message) without changing the appearance of the image at all. Because most blocks of pixels are complex (i.e., with complexity above some threshold, alpha), you can usually replace around 45% of an image with a hidden message. Below, the 300x300 image on the right contains the text of an entire novel, while still looking virtually identical to the vessel image on the left. Note that with BPCS, the hidden message doesn't have to be text. It can be any file type, including another image. You could upload a profile photo to a website that contains a secret image. Or you could embed an image of a turtle inside an image of a turtle inside an image...turtles all the way down. This is an implementation of the method discussed in: Kawaguchi, Eiji, and Richard O. Eason. "Principles and applications of BPCS steganography." In Photonics East (ISAM, VVDC, IEMB), pp. 464-473. International Society for Optics and Photonics, 1999. (pdf).

I am making an interface in Python, I will put the code part of the buttons, which is what matters for this problem.

I tried to put an image in the upper left corner, but other things of the interface are misconfigured, so I could not program it. Below I will leave an example image.

Direct Solution

Create a QLabel widget and use QPixmap to add the picture inside, then use setGeometry to place it on its place. You can add this code inside your initUI() method:
