Basic Video Processing

Hello and welcome to the final blog post. It’s been quite an adventure, and definitely a learning experience for me. I hope this blog will also be helpful to the few eyes that read it haha! I’d also make a quick detour and thank my professor in this class, Dr. Maricor Soriano, for all the wisdom…

Morphological Operations

It’s been a while, but we’re back with a new activity! This post will be on Morphological Operations. Morphology refers to shape or structure. So when we say morphological operations, we basically mean that we’re gonna to apply functions or operations to shapes. In image processing, basic morphological operations are done on binary images to…

Image Segmentation

[Activity 7] Image segmentation is taking a part of the image so that further image processing can be done to it. For example, if we have a grayscale image of a check, we can use image segmentation to find the parts of the check that have writing/text on it. To properly segment the grayscale image,…

2D Fourier Transform Applications and Properties

One property of Fourier Transformations is anamorphism. Since the FT space is in the inverse dimension of the original space, what is wide in one axis will become narrow in the spatial frequency axis. Anamorphism works independently on each axis, so you can expect that patterns with different dimensions along each axis will have a…

Fourier Transform of Images

[Activity 5] Hello again! Today we’ll be using the Fourier Transform on some simple black and white images to get a little more understanding of how Fourier Transform works and how it is useful in image processing and image analysis. It’s been a hassle to keep switching from a Mac partition to a Windows partition,…

Length and Area Estimation

[Activity 4] We are going to estimate the length and area of real-life objects based on an image of the object. This becomes useful for example when we want to know the area of a landmark, town, or city, and the only information available is a map of the city (think of a primitive version…

Scilab Basics

[Activity 3] As part of our AP186 class, we started learning Scilab, which is an open-source software for numerical computation (more can be seen in their site http://www.scilab.org/ ). It is most similar to Matlab, and in addition to our present knowledge of Python, will most definitely help in research work as scientists. Scilab is most…

Digital Scanning

[Activity 2] Weird, where’s Activity 1? Well there isn’t any, since our first activity was to make a movie poster with our faces on them. Unfortunately, I don’t have the picture with me at the moment, but maybe in the future I’ll use it in one of my posts. Our first real activity involves scanning.…
