Millions of engineers and scientists worldwide use MATLAB to analyze and design the systems and products transforming our world.
Such huge usage leads to some very interesting prospects in designing. After all, the list of applications of such a software is endless. The GUI allows the user to graphically view the temperature variation at the end of sensor data acquisition. Use of GUI is advantageous since the user can control illumination patterns while performing other tasks in the PC. Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, or not much less than 20kHz, cannot be heard by most people.
We often need to process these audio signals for various applications. Audio compression is a very good example of speech and signal processing. We use the Internet for various purposes including entertainment.
Audio is common in all entertainment applications. If an audio file size is large, it takes more space to store. This article describes some important audio compression techniques. Conventionally, educational institutions and companies use specialised tools for report cards and certificates generation on a large scale. In this series of four articles, fundamentals, as well as advanced topics of image processing using MATLAB, are discussed.
Cameras are nowadays being provided with more and more megapixels to improve the quality of captured images. With improvement in image quality, size of the image file also increases. One of the applications of image compression with MATLAB using a graphical user interface is described in this project.
This project proposes a technique to compress the captured image to reduce its size while maintaining its quality.Bdo asula ring
This project is available at: Lossless Image Compression. Encoding the information before transmission is necessary to ensure data security and efficient delivery of the information. Huffman algorithm is a popular encoding method used in electronics communication systems. It is widely used in all the mainstream compression formats that you might encounter.
The MATLAB project presented here encodes and decodes the information and also outputs the values of entropy, efficiency and frequency probabilities of characters present in the data stream. This project is available at: Huffman Encoding and Decoding.
Artificial neural network, in essence, is an attempt to simulate the brain. When the user enters the inputs say, p1, p2 and p3 and the expected corresponding outputs say, t1, t2 and t3 in the program, the program trains the system and gives a final weight.
The final weight is computed to get the final expected output. This program is an attempt to understand the basics of artificial neural network and how one can use it for further applications.
This project is available at: Artificial Neural Network Simulation. These calculations waste a lot of time. This circuit design calculator software developed in MATLAB helps you solve, analyse and determine circuit design with capacitors, inductors, resistors, diodes, transistors and other components. The software can provide answers to many complex analogue and digital circuit design problems. This project is available at: Circuit Design Calculator.
Today, almost all applications are expected to be wireless, consume very little power and have high data retention capability.The commands to move the car in forward, reverse, right and left directions are sent from the GUI and processed by Arduino Uno board mounted on top of the car. You can send commands to Arduino to move the car in a specific direction by pressing the corresponding push button in the GUI. The particular push button, when pressed, executes callback function corresponding to that push button in the MATLAB program, car.
Block and circuit diagrams for controlling the robot are shown in Figs 2 and 3, respectively. Arduino Uno board. LD IC. This is a dual H-Bridge high-current motor driver IC. This IC is used since the digital pins of Arduino Uno cannot source enough current to drive the motors of the robotic car.

The coding should be done for feed forward network or bpn for neural part for the given data. Minimum rule sets required for fuzzification of the data for clustering.
Output required in charts and numeric value 9. The basic outline for the neural-fuzzy network. Neural training takes place in the input layer. Minimum tuples required for training. The proposed approach can be divided into two phases: i training phase and ii classification phase. The output of the training phase is a trained classifier capable of predicting binary classification label based on features of MRI scan.
The performance of the trained classifier can be evaluated using measures like accuracy, sensitivity and specificity. The metrics used to determine performance of the trained classifier can be used to determine performance of the proposed approach and its comparison with existing methods. Object detection is the process of finding instances of real world objects such as faces, vehicles and buildings in images or videos.
Face Detection and Pedestrian Detection comes under the Object detection.Stihl 08 specs
Vehicle detection is a part of Object detection. Vehicle detection mainly focus on detecting the vehicle. Automated Vehicle detection will be done by first obtaining the images or videos of vehicles in traffic areas under surveillance.
This can be done by using Image Sensors. After the Image or video being captured the vehicles in the image or video have to detected.
