Pixel Annotation Tool

출처 : https://github.com/abreheret/PixelAnnotationTool

이 툴을 간단히 소개하자면, semantic segmentation에 이미지를 학습시키려면 object별로 pixel을 구분하면 구분은 color 및 label등으로 한다. 이 툴을 통하면 간단히? object 구분하는 label mask 이미지를 만들수 있고, my github에 Semantic-Segmentation에서 자신이 구현하고자 하는 Segmentation을 모델링 할 수 있다

Using pixel annotation tool for generating mask

1. Open tool and select Image folder

2. Mask image

• 1)select the config(json) you want to used
• 2)colour the object with the selected colour; you could zoom in/out by changing value of Resize factor and change size of brush by changing Circle size
• 3)if ther are multiple object then select different colour for each object and colour the object a bit
• 4)colour background with different colour
• 5)check watershed mask and click on watershed
• 6)you could change value of alpha mask to make mask more visible
• 7)fine tune mask a bit if required
• 8)see final mask clearly by setting alpha mask 1.0
• 9)save image
• 10)do it for all images in image

3. Cut take <image name>_color_mask.png for all images and move it to Annotation folder
