Reading an image from a file is fairly straightforward in OpenCV-Python. But a lot of times, we would like to read an image from a URL and process it in OpenCV. One way to do it is to download the image, save it as a jpeg file, and then read it in OpenCV. But that’s too tedious! Who wants to do manual labor? Not me! Another way would be to automatically download the image as a jpeg file using wget and then reading it in OpenCV. This is slightly better, but it’s again a roundabout way of doing it because there is an intermediate step of saving the image on disk. How do we circumvent this and directly load an image from a URL into OpenCV-Python? Continue reading “How To Read An Image From A URL In OpenCV-Python”

Exposing The SSL Encryption
In my previous blog post, I couldn’t discuss much about SSL encryption. I didn’t want to deviate from the main topic. So here, I discuss about the loopholes in the protocol. I have tried to simplify it as much as possible. SSL stands for Secure Sockets Layer and it is a protocol for secure communication over the internet. It just provides enough security to keep attacks at bay, but if someone reeeeally wants to get in, SSL will not be able to stop the attack. Here’s why: Continue reading “Exposing The SSL Encryption”
