Image Analysis Project

Numerous RGB cameras in the commercial sector employ Color Filter Array (CFA) technology. This technology involves an array of red, green, or blue filters placed atop the sensors, usually organized in periodic patterns. The incident light is consequently filtered by each filter, before being captured by the sensor. The typical process of acquiring images utilizes a predefined CFA pattern to allocate a color to each pixel of the sensor. The goal of this code project is to demosaicing these CFA Image.

You can check the report called Image_Analysis_Project_Report_Brice_Convers to find more information about it.

How to use

To use the code project you can move the main_template.py outside the src file and execute it. Or you can also call the run_reconstruction method in you programme.

import src.methods.brice_convers.dataHandler as DataHandler
import src.methods.brice_convers.dataEvaluation as DataEvaluation
import time

WORKING_DIRECOTRY_PATH = "SICOM_Image_Analysis/sicom_image_analysis_project/"

DataHandler = DataHandler.DataHandler(WORKING_DIRECOTRY_PATH)
DataEvaluation = DataEvaluation.DataEvaluation(DataHandler)

def main(DataHandler):

    IMAGE_PATH = WORKING_DIRECOTRY_PATH + "images/"

    CFA_NAME = "quad_bayer"

    METHOD = "menon"

    startTime = time.time()

    DataHandler.list_images(IMAGE_PATH)

    DataHandler.print_list_images()

    DataHandler.compute_CFA_images(CFA_NAME)

    DataHandler.compute_reconstruction_images(METHOD, {"cfa": CFA_NAME})

    #The first agurment (ex: 3) is the image index in the list print by "DataHandler.print_list_images()"
    DataHandler.plot_reconstructed_image(3, METHOD, {"cfa": CFA_NAME}, zoomSize="large")

    DataEvaluation.print_metrics(3, METHOD)

    endTime = time.time()

    print("[INFO] Elapsed time: " + str(endTime - startTime) + "s")

    print("[INFO] End")

if __name__ == "__main__":
    main(DataHandler)
