What is Steganography? Steganography can be defined as the science of hiding the data like file, image, video, or any message to the other file, image, video, or message. In Steganography the useless bits are actually replaced by the useful bits in order to hide the required file into any of the files or data mentioned above. It plays a vital...

What is object detection? Given an image or a video stream, an object detection model can identify which of a known set of objects might be present and provide information about their positions within the image.For example, this screenshot of our example application shows how  objects have been recognized and their positions...
