It has been many years working on digitization, reconstruction and virtual world applications; tested and used various techniques covering almost all aspects in the digital recording workflow. In the recent past years our team has been successfully engaged in a very productive workflow regarding digitization and reconstruction in 3D. Specific [...]
A straightforward approach to do geometric image transformations using MATLAB is to take advantage of the imtransform function available.
First the image is supposed to be within a ‘unity’ rectangle and initial transformation conditions are defined accordingly:udata = [0 1];
vdata = [0 1];
fill_color = 128;
org_rect = [0 0; [...]
I have already kept a note on the procedures needed to cancel a pre-approved or automated PayPal payment in a post regarding Skype but this is a more general problem and I need to remember…
Walk through the menus as follows:
My account > Profile > My Money > My preapproved payments > Update
Here are all the billing agreements that third [...]
Recently I read an interesting book “The Grand Design” by Stephen Hawking and Leonard Mlodinow. Somewhere at the end of the book there was a reference to the well known game of life by John Conway (1970). Although I knew it was implemented by various researchers and is already available in MATLAB with a demo function named `life`, [...]
In a recently posted question @StackOverflow a user asked how to find the maximum Euclidean distance in a binary image produced by Canny edge detection using MATLAB. The original post is here. I report my response here just for archival purposes.
Provided that you have a binary edge image, you need to think of white pixels as points in a 2D s [...]
Just a few days ago I run into a very interesting image processing challenge at StackOverflow. The challenge focused on the detection of a christmas tree in an image (see here for more info).
Since I had a some free time I though I could give it a try… The rules in this challenge were plain and simple and included a dataset of 6 images [...]
