Description

A number of projects, sorted by complexity from lowest to highest, programmed in Python, these projects include processing input images, and handling large amount of complex data and process it and coming with an output according to that data, Projects are explained in details below:

    • vignette(image): Returns True after vignetting (corner darkening) the current image.
    • blur(image,radius=5): Returns True after bluring the image.

• Auditing-datasets:(a Project to analyze data(json and cvs) from airlines company's flights and pilots information and weather reports during those flights and list all violations with details of each violation or write them to a file)

  • auditor/utils.py: (Module providing utility functions for this project.)

    • read_csv(filename): Returns the contents read from the CSV file filename.
    • write_csv(data,filename): Writes the given data out as a CSV file filename.
    • read_json(filename): Returns the contents read from the JSON file filename.
    • str_to_time(timestamp,tz=None): Returns the datetime object for the given timestamp (or None if stamp is invalid)
    • daytime(time,daycycle): Returns true if the time takes place during the day.
    • get_for_id(id,table): Returns (a copy of) a row of the table with the given id.

  • auditor/pilots.py: (Module determining pilot certifications, ratings, and endorsements.)

    • get_certification(takeoff,student): Returns the certification classification for this student at the time of takeoff.
    • has_instrument_rating(takeoff,student): Returns True if the student has an instrument rating at the time of takeoff, False otherwise
    • has_advanced_endorsement(takeoff,student): Returns True if the student has an endorsement to fly an advanced plane at the time of takeoff.
    • has_multiengine_endorsement(takeoff,student): Returns True if the student has an endorsement to fly a multiengine plane at the time of takeoff.
    • get_minimums(cert, area, instructed, vfr, daytime,minimums): Returns the most advantageous minimums for the given flight category.

  • auditor/violations.py: (Module to check violations for a flight lesson.)

    • bad_visibility(visibility,minimum): Returns True if the visibility measurement violates the minimum, False otherwise
    • bad_winds(winds,maxwind,maxcross): Returns True if the wind measurement violates the maximums, False otherwise
