image preprocessing

imagepreprocessing

• Creates train ready data for keras or yolo in a single line
• Makes prediction with using keras model
• Plots confusion matrix

Install

pip install imagepreprocessing

Usage

from imagepreprocessing import create_training_data_keras, create_training_data_yolo, create_only_path_files_yolo, make_prediction_from_directory, create_confusion_matrix

Create training data for keras

source_path = "datasets/deep_learning/food-101/only3"
save_path = "food10class1000sampleeach"
create_training_data(source_path, save_path, img_size = 299, validation_split=0.1, percent_to_use=0.1, grayscale = True, files_to_exclude=["excludemoe","hi.txt"])

File name: apple_pie - 1/3  Image:100/100
File name: baby_back_ribs - 2/3  Image:100/100
File name: baklava - 3/3  Image:100/100

Make prediction with a keras model and plot confusion matrix

images_path = "deep_learning/test_images/food2"
model_path = "deep_learning/saved_models/alexnet.h5"

predictions = make_prediction(images_path, model_path)

class_names = ["apple", "melon", "orange"]
labels = [0,0,0,1,1,1,2,2,2]
create_confusion_matrix(predictions, labels, class_names=class_names)
