Pen plotting is an artform that allows people to use machines to do the physical drawing actions. Typically, pen plotted art is very methodical and full of very percise patterns. The most common kind of pen plotting machine is the XY pen plotter, which draws onto a piece of paper with some kind of pen/marker/brush. Gcode instructions are used to guide the plotter to the proper positions on the paper. 3D extruder-based printers also operate in a similar way but in an additional (Z) dimension. Could you convert one to a XY pen plotter?

In many navigation and layout applications, there is a need for spatial data. Historically, this meant that most hardware choices were radio frequency based - mainly LiDAR or RADAR.

SiamMask ONNX Export Journey

During my masters thesis, I worked on different multiple object tracking (MOT) methods. There is another type of tracking method, single object tracking (SOT), that I always was interested in but never got the chance to try. One such SOT method is called SiamMask, and this blog post will go over how I exported this network to ONNX.

I have been cooking different things for a while, and everytime I tell people this, they always ask a version of "have you cooked something interesting lately"? This is where I fumble through my phone, trying to look for something to show them. They typically lose interest by the time I'm showing them a cake I baked 3 months ago. Maybe this new food blog can help and allow me to organize this hobby in a way I wanted it to be for a long time.

In one of my previous blog posts, I stated that I had sucessfully completed my masters thesis and would post more about what I did. Well, its been overdue but here are the two main papers to come out during my time in the program.

For the past couple of weeks, I've been working on a project that would mimic the behavior of Apple's "CenterStage". As a part of that project, I wanted to explore how neural networks were deployed, accelerated, and utilized on smartphone devices.

In this blog post, I revisit my EmojiCam project and try to rectify some of the major pitfalls the original algorithm had. This rectified version of EmojiCam includes multiscale emojis and better emoji color calibration.

I know I have not posted anything since February of this year. There are a lot of reasons for that, but the biggest reason is I was in the middle of finishing my Masters Thesis. It was one of the most academically challenging things I have done in a while, and I am pretty happy with the results. I will be uploading and writing about some of the results in their own respective articles when the time comes.

Effects of Multiheaded Self-Attention on YOLOv3

For my graduate Deep Learning (DL) class, we had a final project assignment that tasked us to conduct novel experiments on a DL area. I decided to implement a MSA module to a common, generic, fast object detector called YOLOv3. We see improvements in classification but significant decrease in localization performance for most network configurations.

This project was done for fun and was done within 24-hours. EmojiCam takes in a RGB frame and creates a frame with emojis replacing pixels. It runs in real-time and has a very simple image processing pipeline.

This project was done to complete one of my breadth requirements for the Tickle Engineering Honors program. The contents of the project were presented at the 2021 EUReCA Symposium as a poster. To keep proper context, the project was completed within less than a month and is a continuation of adjacent, prior works regarding image degradation and Convolutional Neural Networks.

Image Filters (Thread)

I believe the type of image filters that the majority of public knows of started with the popularization of the social media service, Instagram. With the genesis of Instagram, being able to edit on the fly with aesthetic-satisfying results was imperative for a new type of photo-centric social network. Additionally, Snapchat Lens and its interactivity allowed a new wave of interesting image filters that incorporated 3D meshes and AR.
