Computer Vision News - June 2016

Every month, Computer Vision News shows you a nice trick that will make your work easier… This time, our engineers have decided to tell you how to improve blurry images , something which you often want to do, for instance when you want to display your codes in a paper or share them on a magazine… Let’s say you are having a blurry small image with some text and you want it to appear nicely on a screen so it can be read easily. For example we will take the image with the code snippets that we’ve provided in the May issue of our magazine. Let say that the original image looks as follows, very small and blurry. Stretch it out to a full page width and you will makes things looks even more gruesome: 20 Computer Vision News Trick Improve your blurry images... That’s not very nice. The resolution of the image needs to be increased! But how ? And how much ? We will answer now both these questions. How: we shall give you now 5 lines of Matlab script that will do the trick. How much: nowadays, the resolution of a common mobile phone is somewhere between 1334×750 to 1920x1080. Resolution of common desktop monitors is between 1366x768 and 1920x1080 [source rapidtables.com ] , while tablet resolution is near 2304×1440. What those numbers indicate is how many pixels you have in your screen. That means that we will need about 2300x1500 pixels if we want our image to appear nicely on full screen on either of those devices. So let’s do it!
