If the users are not too familiar with concepts of data structures and dictionaries, I would recommend checking out one of my previous articles to get more familiar with the concept from the link below. If you are following along with the tutorial this far, upon running the following code, you should obtain the following output parameters. # Declaring the essential Characters dict1 = ') Output: Height: 3585, Width: 5378, Number of channels: 3

Below is the code block for performing the following action. The number of channels of an image defines if it is a grayscale image or an RGB image.

In the same code block, we can proceed to read the image that we have previously stored in our working directory as “test_image.jpg.” It is often a healthy practice to analyze the parameters of our image, such as the height, width, and the number of channels.

You can print these two dictionaries to help figure out how they work. The first dictionary will store the ASCII objects as the key along with their respective ids, while the second dictionary does a similar task but vice versa. Firstly, we will declare two dictionary data structures as shown in the code block below. In this section of the article, we will declare all the required variables and parameters to compute the project. Gaining knowledge of this library is one of the most significant steps in mastering computer vision in Python.ĭeclaring and defining the required variables and parameters: If you are not completely familiar with the Open-CV library, I would highly recommend checking out one of my previous articles that cover the entire basics of this concept from the link provided below. # Importing the essential libraries import cv2 import string import os

The OS library is useful for managing functions related to the operating system to save or create files in Windows or another similar platform. The string library can be utilized for handling string data and ASCII values. The most important library module is Open-CV (cv2) for computer vision applications, such as manipulation of images, reading and writing images, and other critical operations. The first step for this project is to import all the essential libraries that will be required to complete the task. Now, without further ado, let us get started with the steganography project.

Before we get started, ensure that you download the above image into your working directory and save it as “test_image” in the. We will divide this section into a few parts to gain an easier understanding of all the essential steps that need to be followed to successfully develop this project.

In this section of the article, we will learn how to encrypt and decrypt secret text data and information by hiding them inside images. In the next section, we will learn in detail how to build this project. You can encrypt your secret data and play along with your friends to decrypt the desired information, provided that both the sender and receiver (destination) share the common keys. In this article, we will work on constructing a fun Python project from which we can understand the basics of steganography and how to hide secret information within an image. In computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. Steganography is the practice of concealing a message within another message or a physical object. Below is the more formal definition of Steganography from the wiki. Once the secret information is encoded within the image, only an expert or the end-user receiving this data with the secret key can decode (or decrypt) this secret information. The art of hiding information and secret data within images by cryptically encoding this information is often referred to as Steganography.

If you want to transmit some kind of secret information to your friend or family and do not want others to really know about it, what might be the best way to do so? - In this article, we will develop a fun Python project that can securely encrypt text information within an image so that it can be successfully transferred to the recipient, who can decode it accordingly. Security and privacy are two major concerns in the modern world.
