English Version. Turns out that I have a MPU6050 (Accelerometer + Gyro sensor) and these days I have gone through the process of learning how to use it. If everything goes well, on this post you will find practical information to configure, calibrate and use this sensor. My “contribution” consists in the development of a…
Versión en Español Turns out that I have been quite busy these days with my master thesis, but thanks God, I am ready to resume this healthy habit. Today, motivated by an article recently published in “Pattern Recognition” [1], I do have the intention of presenting some basics, problems and some simple examples about circle…
Versión en Español Turns out that I have wanted for a long time to do some miniprojects with Arduino and these days, reading about how to do some things with the camera, I found a simple and useful DIY. Initially I was interested in developing something like a remote trigger for the camera, but after…
Versión en Español Turns out that recently I have been taking my first steps into the photography world, and I am discovering a great deal of interesting things I didn’t have think about before. One of the points I have been getting information about is how the auto-focus function works. Besides, some time ago I…
Versión en Español, Turns out that sharing photos through some cloud service is completely normal nowadays and something that I am especially suffering these days. Unless you got a premium cloud service (in which case you would be the first person I meet with one of those), your service could have some limitations regarding upload…
Spanish Version Turns out that there are countless intelligent ways to track an object within an image: using features descriptors, optical flow, colours, kalman filter etc. But, as I am not a genius, and taking advantage of having done a simplified tracking code for a class project, I would like to use it to discuss in…
Versión en Español, Turns out that the last post I published has opened my particular Pandora’s box. There is a whole world of drawing machines there outside and they are so cute that I have the necessity of talking about them. There are several examples and today I would like to show you one of them, known…
Spanish version. Turns out that exams give the time wings. As it usually happens, the exams consume as much time as they can and thus, it is hard to find a free slot to prepare new elaborated posts. However I have done a bit of drawing to catch the breath! Probably due to my daily activity, I…
Spanish version Turns out that I have just woken up and, that counter which is only activated each 21930+-30 hours has moved! (happy new year by the way 🙂 ). The Christmas consequence is a “pending-post” queue waiting for me to have some spare minutes, given by my exams obligations, to post it (and a couple…
Spanish version Turns out that frequently I need a video with specific characteristics in order to test some computer vision algorithms. Obviously, the Internet almost always has a suitable picture for each moment but, in this kind of obsession for learning how to do everything that I manifest, I wonder what exactly is, and how those short…
Spanish version Turns out that computer vision not only works with static images but also with video processing. I am plenty conscious that this post performs a step forward in terms of difficulties, but it is said that the best way to learn concepts is attempting to explain them and, since I want to clarify some details related to…
Spanish version Turns out that when I was about to finish the plate recognition post, I realised that there are some basic operations that are needed to be previously understood and If I describe them within the post it turns endless. As a timely retreat is a victory, I have decided to write a second introductory post with the…
Spanish Version Turns out that there are more computer vision applications around us that we actually realise. Perception as a global concept and computer vision as a specific one, are ideas really used in the real world. Behind such reality there are “simple” things like computers reading your plate number, or more “advanced” uses like computer vision aided cancer detection.…
Turns out that I have a couple of projects in mind and I was looking for which was the best way to modify from different computers the files without too much suffering. I had discarded solutions similar to Dropbox because I intend to work in Virtual Machines with Ubuntu and I considered dropbox not to be…
Turns out that generating documents is one of the most common tasks that I have to do ultimately. With this in mind… What is LaTex?, What does LaTex do?, Why do I use Latex and Why am I so persistent talking all the time about LaTex?. Well, first of all I am not an expert so…
