Activity 3: Image Types and Formats

Image
Usually, when looking or saving images, it wouldn't matter to me what file type should i save it to so long as I am able to see it though my device (phone, ebook reader.  However if I wish to save space, I usually save it in multiple file formats and choose the least file size it was saved to (which is usually jpeg). Image Types So to remedy this, I researched the different characteristics of image formats and types.  There are several known image types: binary, grayscale, truecolor, indexed, high-dynamic range, multispectral, and 3D images.    Examples of these images are shown below: Binary Binary image with corresponding properties using imfinfo()  Grayscale images Grayscale image with corresponding properties using imfinfo() True color images Tr image with corresponding properties using imfinfo() Indexed images Indexed image with corresponding properties using...

Activity 2: Scilab Basics

Image
The first task for the day was to install Scilab 5.3.3... When I tried to download it, imaginge my surprise whet it said it will download after 1hr.  Then Gino was able to download it for only 5 min or less (which was very unfair, I wonder what he did to his laptop...).  Another issue was that everyone was 64-bit so I asked Gino to download the proper installer for me.   Zzzzzz.... (-_-) After several decades... (well, it seemed like decades to me) FINALLY! I was able to install it in my computer.. From my previous classes, using Scilab was actually highly recommended for the fact that it is free (like Python) unlike Matlab.  What is even more surprising is that its programming syntax is similar to Matlab (which I use more often) which made it easier for me to follow. The aim of the activity was to simulate optical phenomena and test algorithms in imaging systems with the use of synthetic images (which are computer-generated images). There were s...

Activity 1: Digital Scanning

Still a little hung-up on a weekend where I got to experience a lot of my 'FIRSTs' (I'll let you dwell on what 'FIRSTs' was I able to experience... :P), I'm finally back to the real world, or am I? From our weekend getaway, I did not bring any laptop with me to prevent myself from doing any schoolwork and enjoy the weekend fully, and now, I am back in front of my laptop to actually catch-up on a days worth of work. NO LAPTOP for 2 DAYS!  I can't even remember the last time I DID NOT use the computer.  We are currently in the era where having a laptop (or internet connection) is almost a necessity since we make reports, graphs, and papers using a computer.  It can also be seen that everything is computerized whether you want to enter a building, read and borrow books, buy stuff, or send important files to somewhere half across the world.  As such, our writing materials (for publication, or plain writing) has evolved from a simple pen and paper to computer...
