One Pixel at a Time

https://behappy.me/generator On the second week of our laboratory discussions, image enhancements were discussed. These kinds of image enhancements lets you generate a function according to your liking or according to what enhancements you want the given image to have and then applying that function to compute for the newly generated value for a certain color channel for every pixel in an image.                                             bear.jpg In an example of image enhancements, our laboratory professor provided us with an image of a bear named bear.jpg. B elow, the following versions of bear.jpg is produced together with a graph of the given function in contrast to the function x = y . bear_dark.jpg bear_inverted.jpg                                ...

https://behappy.me/generator For every course a student takes, it always starts with the basics. Our first topic in the laboratory was an introduction of the course and the basics of  OpenCV  - a C++ library that we will be using the whole semester for digital image processing. As I said the on my previous post, an image is represented as a two-dimensional array of pixels and per pixel has its corresponding values. Furthermore, it is said that a pixel's values represents the three (3) color channels - red, green, and blue. Each value determines the amount of a certain color channel is in that particular pixel. Usually the color channels are in the following order: red, green, and blue but in OpenCV , it is ordered in blue, green, and red. In C++, as long as  OpenCV library is imported ,  an image can be stored in a container called Mat.  For image reading, imread()  function can be used. Other functions such as   imshow()   and ...

We lcome to "One Pixel at a Time"!  https://behappy.me/generator I am Renee Arianne Lat, a BS Computer Science student in the University of the Philippines Los Baños.  https://imgflip.com/images-to-gif "One Pixel at a Time" is a partial requirement for an elective I'm taking this semester. This blog will be all about the things I will learn about the field of Digital Image Processing.  As an introduction, it is said that an image is a matrix of square-shaped pixels and per pixel contains a specific value. Basically, an image is represented by a two-dimensional array of values. Digital Image Processing will be all about editing an image by manipulating each pixel in the array.  I'm very nervous about in taking this course because it's seasonal but at the same time I'm kind of excited so hopefully I'll finish this course with flying colors! Fighting!
