Indic Palm Leaf Manuscript Analysis & Neural Digitization

Ancient Indic palm leaf manuscripts suffer from ink fading, physical decay, and complex character overlap. This project develops a deep learning pipeline combining advanced image enhancement, character segmentation, and convolutional neural architectures to transcribe and classify degraded historical scripts accurately.

Research Collaboration with IIT Tirupati Researchers

Methodology

Employed custom contrast-limited adaptive histogram equalization (CLAHE) with morphological filtering for foreground script isolation, followed by a fine-tuned ResNet and Vision Transformer backbone for multi-class glyph classification.

Dataset

Curated dataset of high-resolution Indic manuscript scans provided in collaboration with IIT Tirupati researchers.

Architecture & Models

ResNet-50, Vision Transformer (ViT), U-Net Segmentation

Outcome: Achieved 94.6% character recognition accuracy on degraded palm leaf specimens, significantly outperforming baseline OCR models on low-contrast historical documents.

High-Performance Limit Order Book & Low-Latency Matching Engine

Modern financial markets require deterministic, sub-microsecond order execution. This research implements a cache-optimized limit order book matching engine in C++ and Python, evaluating price-time priority (FIFO) queues under synthetic high-frequency order flows.

Methodology

Utilized contiguous memory arrays, custom memory pools, and lock-free ring buffers to minimize cache misses and latency spikes during high-burst market volume simulations.

Dataset

Synthetic high-frequency market order flow and historical tick data.

Architecture & Models

Stochastic Hawkes Process, Poisson Order Arrival Simulator

Outcome: Sustained over 2.4 million order matches per second with mean latency under 420 nanoseconds in optimized C++ benchmark environments.

Monte Carlo Simulations for Exotic Option Pricing & Risk Modeling

Evaluated European and Asian option pricing under Black-Scholes and Heston stochastic volatility models using variance-reduced Monte Carlo simulation techniques including antithetic variates and control variates.

Methodology

Simulated 100,000+ stochastic price trajectories via Geometric Brownian Motion and Milstein discretization, analyzing convergence rates and Greek sensitivities (Delta, Gamma, Vega).

Dataset

Simulated market paths and historical S&P 500 equity options volatility surfaces.
