3.4 Functional Requirements • The system should process the input given by the user only if it is an image file (JPG, PNG etc.) • System shall show the error message to the user when the input given is not in the required format. • System should detect characters present in the image. • System should retrieve characters present in the image and display them to the user.
It is a logic optimization used to reduce the area of complex logic in integrated circuits, thus making the circuit more efficient, which is
3.3-Discrete orthogonal transform It is generally used in enhancement of images that have various properties we have many transforms such as: Discrete Hartley, Fourier, Cosine transforms, etc... All of these transforms has similar properties. Every transform has equation for transformation. 3.4-Alpha Rooting Is a method that deals with many of orthogonal combinations as Fourier, Hartley, Haar Wavlet, and Cosine .the mathematics for Alpha Rooting: X ( p, s) α −1 = X ( p, s)
The difference between unclassified and classified imagery is the means in which the image is captured. How an image is captured determines the level of classification. The intelligence community is known to utilize imagery of the classified variety; however, unclassified imagery can be just as helpful to those in the Intelligence community. One of the biggest advantages is the ability to create Imagery Derived Products (IDPs) to share with everyone, regardless of their respective military or civilian affiliations.
New techniques used in the motion picture industry allow the transfer of images from computers onto film. The information may be not only in the form of numbers, but also in words or images. The result is the ability to take information from a variety of sources and store it onto one medium. The need to store tremendous volumes of documents for long periods of time has been a liability since the beginning of the motion picture industry.
Advancing technology is one of the most important factors leading to police officers, among other types of law enforcement, being able to more quickly, and safely, apprehend a criminal. One of these technologies is that of the Automatic License Plate Recognition system, otherwise referred to as the ALPR. According to Inspector Norm Gaumont and Constable Dave Babineau “ALPR was developed in 1992 at Cambridge University in the United Kingdom in response to terrorism… The United Kingdom continues to lead the way when it comes to the use of ALPR technology”. The Automatic License Plate Recognition system operates through two cameras which can be mounted on police cars, vans, stoplights or other stationary objects.
Light 3. Color 4. Sound Here is the explanation of these four tools : 1. Frame:
Eg: heart disease dataset from the UCI repository 3. Data pre-processing: The chosen health care datasets are pre-processed to handle problems like noise, missing and inconsistent data. This step transforms data into a form that is presentable to the data mining techniques. 4. Data mining: This involves the task of analyzing the dataset and extracting the data patterns using various data mining algorithms like classification, regression, association and clustering.
The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure flowchart and acquisition of digital evidence flowchart is shown on Figure 2 and Figure 3 respectively.
1. Define the following terms: GIS; A geographic information system is system made to capture, store, manipulate, analyse, manage, and present spatial or geographical data. FOSS; Free or Open Source Software. FOSS programs have licenses that allow users to freely run the program for any purpose, modify the program as they want, and also to freely distribute copies of either the original version or their own modified version. ILWIS; Integrated Land and Water Information System is a GIS / Remote sensing software for both vector and raster processing.
The issue in the scenario is Photo Manipulation. Photo manipulation is altering or transferring a photograph to make it look more appealing. Some photo manipulations are considered an art form because it involves the creation of unique images. The manipulation of photographs can be done using a variety of software programs like Photoshop, Lightroom, Gimp and many more. Photo manipulation creates an illusion or deception on the original photograph.
The information input is where and how the employee will gather the information or data needed to perform the job. For example, a teacher gets their information by using their personal knowledge and textbook information to perform a lecture in class. The mental processes category examines the cognition aspect of the job. Thus, a psychiatrist must be accurate with their decision making when diagnosing someone. The work input category emphasizes on what tasks, tools, or machines the worker needs in order to perform their
"A picture shows me at a glance what it takes dozens of pages of a book to expound." - Ivan Turgenev The above line written in 1862 are not only true today, but with amplified significance and consequences. The relevance and importance of digital images growing day by day. They are a major source of information exchange in the digital world.
Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.
Digital architecture involves the use of computer modelling, programming, simulation and imaging to create both virtual forms and physical structures. The ways in which architecture is formed, created, presented, and marketed is transforming – in relation to the transition to a digital society. Digital architecture allows complex calculations that delimit architects and allow a diverse range of complex forms to be created with great ease using computer algorithms. Architecture created digitally might not involve the use of actual materials (brick, stone, glass, steel, wood).
