In This article, we will try image segmentation using Mask RCNN. It's the successor of Faster-RCNN. We will use
tensorflow-gpu==1.15 for training purposes. Check the Mask_RCNN Github repository. It's implemented in the TensorFlow framework using
Resnet101 as the default backbone.
Image segmentation is like an advanced form of classification. In Classification, we used to classify pictures into classes.
In the case of image segmentation, we classify each pixel of the image into different classes. The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze.
Self Driving cars has some concept of image segmentation for driving.
This is an implementation of Mask R-CNN on Python 3, Keras, and TensorFlow. The model generates bounding boxes and segmentation masks for each instance of an object in the image. It's based on Feature Pyramid Network (FPN) and a ResNet101 backbone.
# Python3 on Ubuntu sudo apt-get install python3-pyqt5 # PyQt5 sudo pip3 install labelme
Check Labelme Documentation for installtion on winodws & Mac
1.Git clone the Mask-RCNN-Implementation
2.Install the Mask_Rcnn module.
python -m pip install git+https://github.com/matterport/Mask_RCNN
3.Create Data_folder in Root Directory and arrange the folder in the below manner. Divide the Data into 70/30 for
- Data_folder - train - img1.jpg - img1.json - img2.jpg - img2.json ... - val - img3.jpg - img2.json - img4.jpg - img4.json ...
4.Change the configuration according to your Data and System specifications.
# Configuration # Adjust according to your Dataset and GPU IMAGES_PER_GPU = 2 # 1 # Number of classes (including background) NUM_CLASSES = 1 + 1 # Background # typically after labeled, class can be set from Dataset class # if you want to test your model, better set it correctly based on your training dataset # Number of training steps per epoch STEPS_PER_EPOCH = 100
python customTrain.py train --dataset=path_to_Data_folder --weights=coco
python customTrain.py train --dataset=path_to_Data_folder --weights=last
python customTrain.py evaluate --dataset=path_to_Data_folder --weights=last
pip install pixellib
import pixellib from pixellib.instance import custom_segmentation model_path = "Trained_Model_path" image_path = "Image_path" output_path = "output_path" segment_image = custom_segmentation() segment_image.inferConfig(num_classes= 4, class_names= ["BG", "Arduino Nano", "ESP8266", "Raspberry Pi 3", "Heltec ESP32 Lora"]) segment_image.load_model(model_path) segment_image.segmentImage(image_path, show_bboxes=True, output_image_name=output_path)
from PIL import Image from matplotlib import pyplot as plt img = Image.open(output_path) plt.figure(figsize=(12, 12)) plt.imshow(img)
