Let’s say you are work
ing with images for your project. A lot of times, when you have to work across multiple platforms, the encoding doesn’t remain the same. In these scenarios, you cannot process images directly by treating them like 2D matrices. One of the most common image formats you will comes across is JPEG. If you are working on the same platform using a library like OpenCV, you can directly read JPEG files into 2D data structures. If not, you will have to read it into a byte array, process it and then encode it back. How do we do that? Continue reading “Reading JPEG Into A Byte Array”

Good Things Come In Small Packages
We encounter digital images everyday. We see a lot of JPEG files on our computers, cameras, phones and tablets. The actual images are huge and it should actually take up a lot of space to fit in all that data. But somehow our machines are able to compress all those images and store everything compactly. Ever wondered how it’s possible to fit so many images in such small space? How can the JPEG algorithm achieve so much reduction in size without visibly losing the image quality? Continue reading “Good Things Come In Small Packages”
