Interactive 3D Modeling of Indoor Environments with a Consumer Depth Camera

-
The link for the paper can be found here

Introduction
The paper aims to develop a framework that will help reduce the complexities of 3D modelling so that it can be used by normal users. The system uses both color and depth for this, provides feedback and can tolerate human errors (alignment etc) and is capable of complete scene coverage. 
Strengths
  • Lowers the complexity for building 3D models 
  • Makes it possible for non-experts to build dense models in real time on their laptops and gives feedback to the user with cues for alignment 
  • Maps that are generated are metrically accurate (can be used measure dimensions )
  • The authors provide a video demonstration of the capabilities of their system and it seems quiet impressive you can check out the video here -https://www.youtube.com/watch?v=KJ6v37GypoE , this video showcases user interaction (rewind and resume, loop closure detection ), 3D localization and using gestures in generated maps
  • Compares better to existing techniques
  • High localization accuracy
Weaknesses
  • The robustness comes at the cost of too much human supervision while building the model 
  • the study conducted is too small to be conclusive

Photo Tourism - Exploring Photo Collections in 3D

Photo taken from here The Full Paper can be found here  and more information can be found  here Introduction: The authors create a novel photo explorer for browsing and organizing large collections of photographs by exploiting 3D geometry of the underlying scene. Their reason for coming up with the system is that the technology for browsing and organizing large amount of photos is old and will generally just show them as thumbnails and i also feel that this is true.  First Impression: At first I thought that some of the things that the system was trying to accomplish were not that hard to do like assigning a location or, were already done like scene visualization which i thought to be similar to Google's street view. Some features however did sound very interesting like like object based photo modeling which basically gives more similar images of the object  or of a particular item in the scene(In my experience Go...

Why start blogging

Never did I ever think that I would start a blog, I am just not that person. So Why start blogging and what do I even blog about: I love technology, that is one of the reasons I decided to do my Master's in Computer Science and plan to start a career as a software developer soon. While I was doing my Master's I got an exposure to a few things that I really like some of them being Computer Vision - It has become mind boggling to me what the human eyesight is capable of and making a machine reach that level of perfection on such a staggering number of scenarios is simply put a challenging problem and one that I want to learn more about. Robotics - My interest for this field stems from the fact that I have absolutely loved cars ever since I was a kid, and ever since I found about autonomous cars, I developed an interest in robotics as well. I took a robotics course and understood and appreciated the struggle for providing a machine with autonomy. These are not the o...
