Latex with Libreoffice (proposal)
Situation: I think latex is a better way of writing scientific manuscripts and I would like to use it for that purpose. Some prefer to do it with MS word or Libreoffice. This post is about a work-flow that will … Continue reading
EcoIP is out!!!
The EcoIP code has been available since the start of 2012 (approx.). It has been changing and will continue to do so as long as I am involved in automation of ecological measurements. Today marks a milestone in the project … Continue reading
Some out of the box thinking. How we see.
This ted video is really cool Optical illusions. It has some interesting insight on ways to approach flower detection. Things to think about: “… it means that the same image could have an infinite number of possible real world sources…” “… … Continue reading
Interesting annotation app.
One of the next steps within my Ph.D. is to create an annotation tool that can annotate a series of images. This will require capabilities like propagating annotations through time, propagating changes through time and facilitating pan/zoom actions. I recently … Continue reading
The Flower counting algorithm lives
I recently finished a flower counting algorithm and am very happy with the results. While the test was done with an easy set of images (yellow flowers over brown ground), I wanted to celebrate an important milestone in the project with … Continue reading

Handle fixme’s in a latex document.
I’m guessing there are many ways to handle this; this is just the one I feel comfortable with :). I like it because it shows me the things I still need to do in the resulting document. So when I … Continue reading
The average of an angle… (mean of Hue Value)
My solution to this issue was to write a bunch of code to handle the behavior of the average calculation at the 0 and 360 points. It was a pain in the neck, and I probably have it wrong :(. … Continue reading

CENS at UCLA
For my stay abroad I had to come to CENS at UCLA. The advances related to novel methods for collecting and analyzing ecological data is synchronized with what I have been doing for the past couple of years. I arrived … Continue reading
Idea: Getting the color of a flower from a flower
Just wanted to jot this down before I forget it…. I have been working under the assumption that to make a “good” vision algorithm, I should first find an object that is “easy” to detect and then build additional elements … Continue reading
