Model: a partial abstract representation - analyze, communicate, test, document, understanding of the system

computational: time-varying behavior of a system
analytical: math of relationship among variables in a system
non-analytical/descriptive: describe components and their relationships in a system.
1. application: UML models, sysML models, BPMN models
2. Data: relational, network, hierarchical models - OO data models

aggregation and composition

attributes = properties = characteristics = state = fields = variables
object = instance
defining a class = creating objects = instantiation
superclass=parent class=base class
subclass=child class=derived class

class components:

identity=name=type: glass
attributes=properties=data: color, size, fullness
behaviors=operations: fill(), empty(), clean() = method

abstraction
polymorphism
inheritance
encapsulation

functional requirements: The module must

test opencv input/output image
allow to check grand truth image and output image
maintain a library of all comparison SSIM, PSNR, ...
allow to choose different comparison algorithms: PSNR, SSIM, ...

non functional requirements: the module should be ... (maintainability, reliability, usability, availability)

simple library attached to project
fast
update-able

FURPS requirements:

functionality: SSIM, PSNR,
usability: attached to the project as a class test
reliability: assert in C++
performance: real-time
support-ability: simple class with all functions

use cases:

title: developer test image processing functions by see ground truth image and output image differences
primary actor: computer vision developer
success scenario: check and see differences between ground truth image and output image by different matrix such as SSIM, PSNR, ...

user story:

as a computer vision developer i want to test my output image so that I can see ground truth image and my output image differences

classes - objects
relationship between objects
conceptual object model
CRC card = CRH card
1. Class (name of class) = Component : class test histogram
2. responsibility = responsibility : test two image histogram and compare them
3. collaboration = Helper= get ground truth image and compare it with output function

classA *myclass=new classA()

constructor : we want to set value at the beginning and not problem with null or 0 or ... initialization

destructor = finalizer

static variable: shared across all objects in a class = shared variable = class variable = classA.staticVariable

SubClass(int foo, int bar): SuperClass(foo){}

interface: list of methods = <<name>> = ---->
