Neuvième: Video Processing

Welcome to the last blog of my Applied Physics 186 class!!! Who would’ve thought that the my first image processing blog was already 4 moths ago? Time sure flies so fast! I remember talking about how nervous I am when it comes to programming on my Scilab blog; and I never expected how now, I can…

Huitième: Morphological Operations

Hi reader! It’s been a long while since my last blog entry; I have been busy with my other courses and it also it took me a while to figure out the next activity. Anyway, the topic for this entry is all about morphological operations. This is an entirely new topic so we won’t be…

Septième: Image Segmentationz

From my previous blogs, we have seen an unconventional way of editing images by looking at their frequencies in the Fourier plane and blocking the unwanted ones. Now, we will look into another way processing image; via segmentation. Basically, image segmentation is the selection of a region(s) of a given image based on their similar features…

Sixième: Properties and Applications of the 2D Fourier Transform

Good morning/afternoon/evening!! Today’s blog is still about Fourier transform (or FT – I shall use this notation for the rest of my blog!); and the introductory theorems as well as some basic exercises and examples can be found in my previous blog. That being said, I will explain things on the assumption that the reader…

Cinquième: Fourier Transform Model of Image Formation

Essentially, the Fourier transform of a function x(t) in time domain gives us the function X(f) in the frequency domain. Thus, applying this to a time signal allows us to obtain the frequencies comprising it. In the context of image formation, we use the Fourier transform to decompose the image to its sinusoidal components, allowing…

Quatrième: Length + Area Estimation

Good morning/afternoon/evening reader! First and foremost I want to thank you for taking time to read this blog and I hope I that I could impart something with my work. Also, sorry for any lapses or mistakes I might accidentally mention in this blog, this has been a hell of week. Comments and suggestions regarding this…

Troisième: Scilab <3

Besides electromagnetism, programming is the topic I am most scared of. That is why I automatically panicked after hearing that we are to produce something using Scilab, a new programming language (for me). I was like: ‘heck, it took me two semesters to even get used to programming in python, how am I to do…

Deuxième: Digital Scanning

To be honest, this is one of those few happy moments where I didn’t fret (not even a little bit) upon the announcement that the activity is to be done individually. This is probably due to the fact that this is just the second activity; and the difficulty of the tasks is designed to gradually…

RHR

Electromagnetic induction, the process where a conductor is placed in a changing magnetic field to produce a current, was the main concept of our study and experiment last Monday. The experiment has four main parts; and we used two solenoids of different radius as a conductor and a magnet as the source of the changing…

NS SN SS NN

After doing experiments that are mainly governed by the concept of electric field, we have now moved on into the concept of magnetic field. As a child, we all have been fascinated on how a magnet works, and little do we know back then that it can all be explained by physics. The reason why…
