Activity #9 – Basic Video Processing

Welcome to the last activity blog post for the Applied Physics 186 Experience. So far, we have been doing a lot of single image processing: from digital scanning to morphological operations. And yes, we have managed to process a lot of images. It is now time to integrate what we have learned and do video […]

Activity #8 – Morphological Operations

Previously, in Activity #7, I started talking about morphological operations, where manipulations were done on binary images. Morphology refers to shape and structure, and morphological operations tend to make adjustments on an object’s shape and structure through the use of structure elements. Basically, binary images are those images having only image values of either 0 and […]

Activity #7 – Image Segmentation

Digital image processing is not only engaged with image enhancement and analysis, but also with morphological operations. These operations allow the removal of imperfections found in binary images, such as when simple thresholding is applied to the grayscale version of my fingerprint in Activity #6. Moreover, the conversion of grayscale images into binary images involves […]

Activity #6 – Properties and Applications of the 2D Fourier Transform

It is time to continue our work with the mighty Fourier Transform. Previously, on Activity #5, I showed how the Fourier Transform is related to a simple lens system, in which the object (which is the image generated using Scilab) is placed at the focus of the image. The corresponding image of the lens system is the […]

Activity #5 – Fourier Transform Model of Image Formation

Digital image manipulation and image processing have never been complete without the famous Fourier Transform. Developed by Joseph Fourier (1768-1830), the Fourier Transform (FT) has not only led to advancements in mathematics such as determining solutions of differential equations, but also has been used for optics, sound and acoustics, signal processing (acquisition of signal frequencies), […]

Activity #4 – Length and Area Estimation in Images

Digitization has not only helped in generating synthetic images and digital reconstruction of old graphs and images, but also became essential in the estimation of object size using 2-D images. This has led to great improvements in research and development because not all objects are measurable with the cheap equipment. Measuring the size of microscopic specimen like […]

Activity #3 – Scilab Basics

Today, we are going to learn a very useful programming language, which is called Scilab. It is a high level, scientific programming language which is an acceptable substitute for Matlab. Best of all, it is FREE! So what’s good about Matlab and Scilab? Most computer-based and software businesses hire computer programmers who are proficient in Matlab. Matlab allows […]

Activity #2 – Digital Scanning

In today’s digital era, computers have been essential tools not only in easy manipulation of data, but also in the restoration of old files and images. While it may seem so far-fetched, one can really restore pictures painted many centuries ago and produce a much cleaner version of the said image. Many professionals such as businessmen, doctors, […]
