+# cv-analysis - Visual (CV-Based) Document Parsing
+
+parse_pdf()
+This repository implements computer vision based approaches for detecting and parsing visual features such as tables or
+previous redactions in documents.
+
+## API
+
+Input message:
+
+```json
+{
+  "targetFilePath": {
+    "pdf": "absolute file path",
+    "vlp_output": "absolute file path"
+  },
+  "responseFilePath": "absolute file path",
+  "operation": "table_image_inference"
+}
+```
+
+Response is uploaded to the storage as specified in the `responseFilePath` field. The structure is as follows:
+
+```json
+{
+  ...,
+  "data": [
+    {
+      'pageNum': 0,
+      'bbox': {
+        'x1': 55.3407,
+        'y1': 247.0246,
+        'x2': 558.5602,
+        'y2': 598.0585
+      },
+      'uuid': '2b10c1a2-393c-4fca-b9e3-0ad5b774ac84',
+      'label': 'table',
+      'tableLines': [
+        {
+          'x1': 0,
+          'y1': 16,
+          'x2': 1399,
+          'y2': 16
+        },
+        ...
+      ],
+      'imageInfo': {
+        'height': 693,
+        'width': 1414
+      }
+    },
+    ...
+  ]
+}
+
+```
+
+## Installation
+
+```bash
+git clone ssh://git@git.iqser.com:2222/rr/cv-analysis.git
+cd cv-analysis
+
+python -m venv env
+source env/bin/activate
+
+pip install -e .
+pip install -r requirements.txt
+
+dvc pull
+```
+
+## Usage
+
+### As an API
+
+The module provided functions for the individual tasks that all return some kind of collection of points, depending on
+the specific task.
+
+#### Redaction Detection (API)
+
+The below snippet shows hot to find the outlines of previous redactions.
+
+```python
+from cv_analysis.redaction_detection import find_redactions
+import pdf2image
+import numpy as np
+
+pdf_path = ...
+page_index = ...
+
+page = pdf2image.convert_from_path(pdf_path, first_page=page_index, last_page=page_index)[0]
+page = np.array(page)
+
+redaction_contours = find_redactions(page)
+```
+
+## As a CLI Tool
+
+Core API functionalities can be used through a CLI.
+
+### Table Parsing
+
+The tables parsing utility detects and segments tables into individual cells.
+
+```bash
+python scripts/annotate.py data/test_pdf.pdf 7 --type table
+```
+
+The below image shows a parsed table, where each table cell has been detected individually.
+
+![Table Parsing Demonstration](data/table_parsing.png)
+
+### Redaction Detection (CLI)
+
+The redaction detection utility detects previous redactions in PDFs (filled black rectangles).
+
+```bash
+python scripts/annotate.py data/test_pdf.pdf 2 --type redaction
+```
+
+The below image shows the detected redactions with green outlines.
+
+![Redaction Detection Demonstration](data/redaction_detection.png)
+
+### Layout Parsing
+
+The layout parsing utility detects elements such as paragraphs, tables and figures.
+
+```bash
+python scripts/annotate.py data/test_pdf.pdf 7 --type layout
+```
+
+The below image shows the detected layout elements on a page.
+
+![Layout Parsing Demonstration](data/layout_parsing.png)
+
+### Figure Detection
+
+The figure detection utility detects figures specifically, which can be missed by the generic layout parsing utility.
+
+```bash
+python scripts/annotate.py data/test_pdf.pdf 3 --type figure
+```
+
+The below image shows the detected figure on a page.
+
+![Figure Detection Demonstration](data/figure_detection.png)
+
+## Running as a service
+
+### Building
+
+Build base image
+
+```bash
+bash setup/docker.sh
+```
+
+Build head image
+
+```bash
+docker build -f Dockerfile -t cv-analysis . --build-arg BASE_ROOT=""
+```
+
+### Usage (service)
+
+Shell 1
+
+```bash
+docker run --rm --net=host --rm cv-analysis
+```
+
+Shell 2
+
+```bash
+python scripts/client_mock.py --pdf_path /path/to/a/pdf
+```
