Add Automatic Tags Assignment Tools and Improve Face Recognition Engine for digiKam

digiKam is an advanced open-source digital photo management application that runs on Linux, Windows, and macOS. The application provides a comprehensive set of tools for importing, managing, editing, and sharing photos and raw files.

The goal of this project is to develop a deep learning model that can recognize various categories of objects, scenes, and events in digital photos, and generate corresponding keywords that can be stored in Digikam's database and assigned to each photo automatically. The model should be able to recognize objects such as animals, plants, and vehicles, scenes such as beaches, mountains, and cities,... The model should also be able to handle photos taken in various lighting conditions and from different angles.

(Week 1 - 2)

In this phase, I focus mainly about offline analysis, this analysis aims to create a Deep learning pipeline for object detection model

May 29 to June 11 (Week 1 - 2) - Experimentation on COCO dataset

DONE

• Constructing data sets (training dataset, validation dataset and testing dataset) firsly in some common kind of objects as person, bicycle, car.
• Preprocessing data, studying about construct of COCO dataset which is used for training dataset and validation dataset.
• Research and create model pipeline for all YOLO version in python.
• Evaluate performance of YOLO methode by considering some evaluated metrics.

TODO

Construct of COCO dataset format

The Common Object in Context (COCO) is one of the most popular large-scale labeled image datasets available for public use. It represents a handful of objects we encounter on a daily basis and contains image annotations in 80 categories, with over 1.5 million object instances. You can explore COCO dataset by visiting SuperAnnotate’s respective dataset section.

COCO Dataset Formats

COCO stores data in a JSON file formatted by info, licenses, categories, images, and annotations. For downloading COCO dataset reason, I used the instances_train2017.json and instances_val2017.json files.

   "info": {

       ...   
   ],
   "categories": [

       {

           "name": "cat",
           "supercategory": "animal"
       },
       ...
   ],
   "images": [
       {
           "id": 0,
           "license": 1,
           "file_name": "<filename0>.<ext>",
           "height": 480,
           "width": 640,
           "date_captured": null
       },
       ...
   ],
   "annotations": [
       {
           "id": 0,
           "image_id": 0,
           "category_id": 2,
           "bbox": [260, 177, 231, 199],
           "segmentation": [...],
           "area": 45969,
           "iscrowd": 0
       },
       ...
   ]

So to extract necessary information, we have used the COCO API who assists in loading, parsing, and visualizing annotations in COCO. The API supports multiple annotation formats
