Introduction – There is more to the picture for the eye In the last post we extracted data from images and processed it. In this post we will cover the topic of image manipulation based on external data. This is useful because it allows us to combine data sets into a single point of observation. I’ll go through how to take an image and convert it based on variable conditions. I’ll also cover how to overlay text data into an…
Introduction – processing images with ImageMagick I first posted about ImageMagick in early June, last year. Then late November, I covered the steps to install it and use it on RPi. The features of ImageMagick are fairly extensive, I won’t go into all of them here. As a guide, I recommend Michael Still’s book titled “The Definitive Guide to ImageMagick” through APress publishing. For additional information, you may want to look at Sohail Salehi’s book titled “ImageMagick Tricks” from Packt Publishing. ImageMagick is defined on…
Introduction – I can’t hear a word you’re saying The RPi has all sorts of topics but when it comes to big audio dynomite, forgedaboutit. When the image and video processing topics were outlined at the onset of the RPi studies, I didn’t give sound processing any thought. However, as the weeks progressed, I began to realize that the RPi could over shadow the Arduino as the platform of choice in the sensor helmet project. One of the key sensors…
