# Chart Analyzer

Chart Analyzer enhances the <mark style="color:purple;">**ASKNOEL**</mark> framework by enabling the processing of **image-based market data** and integrating it with **structured numerical** and **textual insights**. By leveraging **computer vision** and **Optical Character Recognition (OCR)**, this tool allows for **technical analysis** on chart screenshots, blockchain visualizations, and other graphical data representations, enabling more comprehensive insights.

***

#### <mark style="color:purple;">**Key Features**</mark>

* **Chart Pattern Recognition** – Detects technical patterns like **candlestick formations**, **trend lines**, **moving averages**, and **resistance levels**.
* **Blockchain Visualization Analysis** – Extracts **transaction flow data** from blockchain explorer screenshots for deeper blockchain analysis.
* **Optical Character Recognition (OCR)** – Reads and processes **numerical** and **textual data** from dashboards, reports, and graphical data.
* **Pattern Detection** – Identifies key trading signals such as **head-and-shoulders**, **double tops**, **flags**, and more.
* **Cross-Modality Fusion** – Combines visual insights from charts with **API-based financial** and **on-chain metrics** for a comprehensive analysis.

***

#### <mark style="color:purple;">**Technical Overview**</mark>

The Chart Analyzer operates in three stages: **image preprocessing**, **feature extraction**, and **AI-powered reasoning**.

* **Preprocessing** – Resizes images and reduces noise for optimal **OCR** and **model detection**, converting visual elements into structured datasets.
* **Feature Extraction** – Utilizes **CNN-based models** (like **YOLO**, **OpenCV**) for pattern recognition, alongside **Tesseract OCR** or equivalent frameworks for extracting **textual data**.
* **AI-Powered Reasoning** – Interprets extracted data using **ASKNOEL’s LLM-backed processing**, combining it with insights from **CoinGecko  and CoinMarketCap API** , **on-chain metrics**, and **sentiment analysis** tools.
