SOFTWARE TESTING
Testing is the procedure of assessing a framework or its component(s) with the expectation to find that whether it fulfills the predefined prerequisites or not [23]. This action brings about the genuine, expected and contrasts between their outcomes. Software testing is an examination led to furnish stakeholders with information about the superiority of the product or facility under test. Software testing can likewise give a goal, free perspective of the software to permit the business to acknowledge and comprehend the dangers of softwareimplementation.There are numerous ways to deal with softwaretesting, yet powerful testing of complex products is basically a procedure of examination

The tester needs to observe inside the source code and figure out which unit/piece of the code is performing improperly.
6.1.2 Black box testing
The method of testing without having any information of the internalfunctioning of the application is calledblack-box testing. The tester lacks awareness of to the system designplan and does not have admittance to the source code. Usually, whencarrying out a black-box test, a tester will work with the application 's user interface by giving inputs and observing outputs without the concern ofwhere and how the inputs are processed.
6.1.3 Grey box testing
Grey-box testing is anapproach to test the application with having constrained information of the internal functioning of an application.
6.2 Levels of testing
Levels of testing consist of the distinct approaches that can be used while leading Software Testing.

There are two techniques of performing Integration Testing those are Bottom-up and Top-Down Integration testing.
6.2.3 System Testing In system testing tester tests the system as a whole. When all the application components are integrated, the system all in all is tried to see that it meets Quality Standards.

This result with an image enhanced in contrast sometime this enhancement results with ugly artifacts. 3.5- Logarithmic Transform Domain Transform Domain allow us or gives us the ability to show the frequency content of the image, however it is uninformative or compacted. In figure (3) this will be obvious .By working on the problem we discovered that the solution is to take the logarithm of the image.

Only one condition $Cin A$ can be extit{true} at the same time and no state transition without being specified by a condition is possible. If condition $C_{i,L_j}$ is not extit{true} any more (due to the proceeding of the assembly operation), there is a fallback to state $S_{j,L_i}$ and all conditions are evaluated to determine the current substate. An exemplary decomposition tree containing different hierarchical levels, multiple states per level and conditions for state transition is given by Fig.~

A collection $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}}$ is monotone if $B\in\mathbb{A}$ and $B\subseteq C$ implies $C\in\mathbb{A}$. An access structure is a monotone collection $\mathbb{A}$ of non-empty subsets of $\{P_1,P_2,...,P_n\}$, i.e., $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}} \setminus\{\emptyset\}$. The sets in $\mathbb{A}$ are called the authorized sets, and the sets not in $\mathbb{A}$ are called the unauthorized sets}. In our settings, attributes will play the role of the parties such that the access structure $\mathbb{A}$ will contain the authorized
