Tkinter is a Python library which is used to create and develop GUI-based applications.Let us suppose that we have to create an application such that we can show or hide the widgets. In this section, we will display images using both PhotoImage and Pillow libraries. # text recognition import cv2 import pytesseract. Then, compress this folder and save it as "secret.zip". Python program to hide the intended information within any image/audio/video and also decode images. For encoding, select any image, this image will be converted into png format. Let's start off by implementing a function to convert any type of data into binary, we will use this to convert the secret data and pixel values to binary in the encoding and decoding phase: def to_bin(data): """Convert `data . In the first part of this tutorial, we'll discuss what a seven-segment display is and how we can apply computer vision and image processing operations to recognize these types of digits (no machine learning required!). Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more. Step 3: Next open the Terminal. computer. DIP focuses on developing a computer system that is able to perform processing on an image. from PIL import Image def encode_image(img, msg): """ use the red portion of an image (r, g, b) tuple to hide the msg string characters as ASCII values the red value of the first pixel is used for length of string """ length = len(msg) # limit length of message to 255 if length > 255: return False # use a copy of image to hide the text in . The following section mainly focuses on the step-by-step approach of the hide and reveal process with the help of a Python script. Use mask image. RGB is considered an "additive" color space, and colors can be imagined as being produced from shining quantities of red, blue, and green light onto a black background. Step 2: Open the file or Image Step 3: Encode some text into the source Image & then save it. Recognizing digits with OpenCV and Python. Start the console in the directory with the python script file (I called mine stego.py) and have an image file ready to manipulate. Implementation of above steps: >>> from stegano import lsb >>> secret = lsb.hide ("sample.png", "Python is dangerous be careful") >>> secret.save ("sample_secret.png") Now if you look at the project folder you will realize there is a new image with the name sample_secret.png.
