annt: Simple annotation tools for object detection task.

Project description


Simple annotated file loader for object detection task.


Various tools have been developed so far for object detection tasks. However, there are no standard in annotation tools and formats and developers still write their own json or xml parser of annotation files. 'annt' resolve this problem. Once you annotate image on annt webapp, you can load annotation images immediately and focus on the essential AI development.

Usage and Example

import annt

# annotations is list of annotation data
annotations = annt.load('~/Dropbox/app/project_name')

# Display ths information of each annotation file.
for a in annotations:
  image = a.image  # opencv2 image array
  boxes = a.boxes  # list of bounding boxes

  height, width, colors = image.shape  # you can

  for box in boxes:
    # Tag information (str)
    print(f'~ tag name : box.tag ~')

    # You can get coordination information of the box by two methods,
    # Left Top Style and Edge Style.
    # Coordination information based on left top of the box. (Left-Top Style)
    print(f'x : {box.x}')
    print(f'y : {box.y}')
    print(f'w : {box.w}')
    print(f'h : {box.h}')

    # Coordination information based on the distance from each edge of the image. (Edge Style)
    print(f'left : {box.left}')
    print(f'right : {box.right}')
    print(f'top : {}')
    print(f'bottom : {box.bottom}'

    # If you change these coordination properties, all of them will recomputed.
    box.w = 300  # This operation will also change box.right property.
