I love experimenting with emerging technology. Most of my experiments still await a sponsorship to be productized. Here lies the selection that could get through.
Generation of salient contours using live video
In various implementations, a computing device is configured to provide a live preview of salient contours generated on a live digital video feed. In particular, a designer can use a computing device with a camera, such as a smart phone, to view a real-time preview of salient contours generated from edges detected in frames of a live digital video feed prior to capture, thereby eliminating the unpredictability of salient contours generated from a previously captured image. In some implementations, the salient contours are overlaid on a greyscale conversion of the live digital video feed for improved processing and visual contrast. Other implementations modify aspects of edge-detecting or post-processing filters for improved performance on mobile computing devices.
Architecture for low overhead customizable routing with pluggable components
A modular IOT enabled router with user controllable and pluggable modules. The architecture of the router and plugins allow users to install packet level and application level modules at real time without affecting the latency and router performance. The installed modules are executed in parallel in their own executing unit and in the predefined or user-specified order. The leveled architecture allows fine-grain control of the routing and forwarding internals like QOS, deep packet inspection, encryption, traffic flow control, and traffic filtering via packet level modules. At the same time, it allows running service like a proxy, firewall, web acceleration, ad blocking via application level modules. The full control provides an easy interface for a developer to write plugins for new protocols, SDN, IOT, and user applications and run them in separate controlled execution engine without affecting the core router engine that is running security.
Ever tried calling C++ from Node or Electron. Hate native modules because of the compilation and maintenance issues. This talk is all about the solution to this problem - N-API that is stable with node 10. C++ to Node.js interop is a lot of fun.
Async-await even though is called as syntactic sugar, is much more. It enables many of the classic design pattern which were reserved for synchronous code not with async ones. Some ideas that were too complicated to implement with synchronous code are very easy with async. It has given new definitions to methods like memoize and also to wrapping methods for performance measurement. In this talk Atishay will discuss the new design patterns enabled by async-await. This talk is about the tricks that are too complicated to write with traditional JS code but are extremely easy to write with async. Open your eyes to modern JS - things that we were missing from right under our nose because we did not see async await the way it should have been - but instead as syntactic sugar.
When we think of node - we think of the server. Node is much more. It is the best solution for any I/O bound operations - even background processes running on customer machines. In this talk, Atishay will present the architecture of a unique node based application - a background process that acts like the browser’s “service worker” - downloading and caching resources even before the page is requested. Getting consistent, fast and effective performance based on network based data where the user can be offline is tricky - this talk will show how it is done. This talk will present the key components of the API that can provide cloud native experiences successfully at scale. Atishay works on Adobe’s CCXProcess, a unique application that is a node reverse proxy server, providing data driven by the server onto machines that can be offline for major parts of the day.

Architecture for High Density RFID Inventory System in Internet of Things
This paper proposes a novel architecture of Internet of Things (IOT) implemented using RFID. Our proposed architecture solves the problem of over-loading as the load on the RFID Tag reader is the total number of changed objects rather than the actual number of objects present. Our architecture is based on EPCglobal Network with some assumptions and modifications. We have discussed in details the components and working of our model. We have also discussed the physical implementation of our model taking the examples of two sample applications one for the retail system and other for smart home applications and their performance results have been tabulated and represented graphically.
Impact of Coordinator Mobility on the throughput in a Zigbee Mesh Networks
Zigbee (IEEE 802.15.4) standard interconnects simple, low power and low processing capability wireless devices. The Zigbee devices facilitate numerous applications such as pervasive computing, national security, monitoring and control etc. An effective positioning of nodes in a ZigBee network is particularly important in improving the performance (e.g., throughput) of ZigBee networks. In the wireless sensor network (WSN) literature, the use of a mobile sink is often recommended as an effective defense against the so-called hot-spot phenomenon. But the effects of mobile coordinator on the performance of the network are not given due consideration. In this paper, we perform extensive evaluation, using OPNET Modeler, to study the impact of coordinator mobility on ZigBee mesh network. The results show that the ZigBee mesh routing algorithm exhibits significant performance difference when the router are placed at different locations and the trajectories of coordinator are varied. We also show that the status of ACK in the packet also plays a critical role in deciding network performances.
Modified Epc Global Network Architecture of Internet of Things for High Load Rfid Systems
This paper proposes a flexible and novel architecture of Internet of Things (IOT) in a high density and mobility environment. Our proposed architecture solves the problem of over-loading on the network by monitoring the total number of changed objects changing global location crossing the fringe boundaries rather than the actual number of objects present or those that move within the local area. We have modified the reader architecture of the EPCglobal Architecture. The components and the working of the model has been illustrated in detail. We have also discussed the physical implementation of our model taking the examples of a smart home sample application and the performance results have been tabulated and represented graphically.
Question Answering is a very important cornerstone of natural language processing where a machine should be able to understand human language to an extent that an individual could ask questions to the machine in the language he/she understands and then get the answers back in the same language without the involvement of experts. In this project we evaluate a neural network based Question Answering system using a simple model and see how a very basic model performs on the StanfordQuestion Answering dataset.
Generic 3D reconstruction from a single image is a difficult problem. A lot of data loss occurs in the projection. A domain based approach to reconstruction where we solve a smaller set of problems for a particular use case lead to greater returns. The project provides a way to automatically generate full 3-D renditions of actual symmetric images that have some prior information provided in the pipeline by a recognition algorithm. We provide a critical analysis on how this can be enhanced and improved to provide a general reconstruction framework for automatic reconstruction for any symmetric shape.
Artificial Intelligence is becoming instrumental in a variety of applications. Games serve as a good breeding ground for trying and testing these algorithms in a sandbox with simpler constraints in comparison to real life. In this project, we aim to develop an AI agent that can solve the classical Japanese game of Sokoban using various algorithms and heuristics and compare their performances through standard metrics.
After knowing the basics of programming, one should know the assumptions and constraints of the domain. It doesn’t matter what language or tooling is needed. You can get upto speed quickly.
