About me

Hello, my name is
Aji Resindra Widya

I am an Indonesian who is currently living in Japan, currently pursuing a PhD at Okutomi-Tanaka Lab in Dept. of Systems and Control Engineering, School of Engineering, Tokyo Tech. My supervisor is Professor Masatoshi Okutomi. I was working very closely with (ex-)Assistant Professor Akihiko Torii. Nowadays, I am working closely with the new Assistant Professor Yusuke Monno. My research, in general, is about 3D reconstruction from a collection of 2D images. In computer vision, we call it structure-from-motion. Specifically, I am working on 3D reconstruction on medical dataset, i.e, gastric endoscopy. Not only working with hand-crafted method, I am also working with deep learning-based ones. My hobby is photography and feel free to look around my portfolio. If you find that my works are good and interested to use my service or my photographs, feel free to contact me through one of the channel i provide in the side bar.

A bit about my expertise

In everyday life, I am a student working on set of computer vision problems, juggling between some programming language to tackle computer vision problems or just for fun. I deal with with Python and MATLAB a lot and I consider it them as my main programming language. In python, I deal with multiple vision library such as Pillow, openCV, and open3D. I also use both PyTorch and TensorFlow but honestly, I only fluent in PyTorch. About other programming language, I also have experiences with C, C++ (both are for microcontroller programming), C# (Unity), HTML, JavaScript, CSS, and PHP (for this website!!).

Outside my life as a student, I use my time to contribute in Indonesia Student Association and do photography as my hobby. Though my journey with camera started when I was in junior high school with my Mom's nikon point-and-shot camera, I did not see it as a hobby back then. I even thought "Nah it's not my thing" haha. I started to put meaning (and effort) in my photograph not until the early of 2017. From there, I started learning Lightroom, Photoshop, and any related stuff. Although I do photography casually, I always strive to become a better photographer. If you found that my works are worthy for a cup of coffee, you can always contact me.
