Electronics and Communication Project Report on JPEG Image Compression

Even after the development in the data transfer rates and bandwidths the transfer has become very costly in the applications has the image contains a lot of information. So there is need for compression techniques where the image will be encoded in a format and is transmitted over the network. The image will be decoded by a decryption process by which the original image will be obtained. There are various image compression techniques available. In this paper we will look into JPEG image compression technique and how the encryption and decryption algorithms for transmitted the image.

Brief on JPEG compression algorithm:

Image which carries information in the form of rectangular array of dots called as pixels. Depending on the pixel value the color of it is identified. Here in JPEG image compression method the encoding process is done over where the original image is divided into 8X8 size blocks of sub images. Here DCT is performed on each image separately and the resultant is divided with the quantization matrix.

The obtained value is made into one dimensional data for obtaining this we can apply zig zag coding, arithmetic or a by applying Huffman coding algorithm. To obtain the original image the reverse mechanism is applied in the decoder. Here we use a source encoder in the image compression model so as to reduce the redundancy present in the input image. If any data loss occurs we can measure the data loss by using fidelity criterion and apply it the algorithm to obtain the image.

Conclusions:

By using image compression the transmitted data gets decreased by which we can transmit the data by using a low frequency signal. By using JPEG compression technique the image gets encrypted which occupies less space and it does not vary the quality of the image when the original image is restored.

ECE Project Report on Microcontroller Based Irrigation System

Introduction to Microcontroller Based Irrigation System Project:

Due to insufficient rains and lack of proper storage reservoirs there is a need to use the limited water resources effectively. By using microcontroller based irrigation system the water the wastage of water gets reduced as the water is directly supplied near the roots. But it is very difficult to supply water only where there is a requirement, so by using an embedded based microcontroller design it is possible. In this paper we will look into the various microcontroller based irrigation methods.

Brief on the design and working:

To make a design we should look into the type of soil and the amount of water to be supplied for each plant and the time intervals to follow for supplying water. We will be using temperature and moisture sensors which will be buried under the soil each line of drip. When the temperature and the moisture are reached to the required point then they transmit a signal to the microcontroller which drives the relays by making the pipe valves to turn off.

This design can be implemented to sprinklers, drip pipes and rotary systems. Based upon the information given by sensors the microcontroller turns the pipes on or off for supply of water to the plants. For this design we will be using an 89C51 microcontroller which has 8KB of flash memory which is best suited for programming our application. The microcontroller program is written in embedded c and is loaded into the flash memory by using keil software. A DC motor is used for regulating the flow of water through the pipes. Amplifiers are connected to the sensors so as to energize the out coming signal the sensors.

Advantages:

This design is a low cost model and it can be easily installed. By employing this design we can reduce manpower and we can look after the water supply very easily. By using drip irrigation the wastage of water gets reduced and by supplying required amount of water to the plants we can yield more. This is error free design as we are using a microcontroller for monitoring the system.

Segmentation of Pathological and Healthy Tissues with Reduced Weighted Vectors Using Hybrid Intelligence Techniques

For a doctor to make a better diagnosis of the tissues he needs perfect repots of the pathological tissues. There are various segmentation methods followed for obtaining the pictures but the proposed algorithm is better than other methods. The proposed method is for detection of pathological tissues and normal tissues and CSF of human brain buy MRI. We will use hybrid intelligence technique by which we can achieve high resolution pixels of the pathological tissues. In this paper we will discuss how we can pictures of the pathological tissues by employing weighed vectors execution method in magnetic resonance method.

Brief on the working algorithm:

In human body the healthy tissues have the ability to control their growth and their divisions and they have a similar array of structure whereas the tumors have capability to regenerate and we can differentiate so that we can identify the healthy and effected tissues. The magnetic resonance technique is capable of showing the difference between the healthy tissues and pathological tissues by using non invasive technique by exposing ionized rays and we can get high contrast images with a good pixel resolution.

Here clustering method is applied on the obtained data which has the capability of processing a grouped data where the similar group of data within the cluster is maximized and the similarity of the data with the other clusters maximized which helps in pattern recognition in an image. Here hybrid intelligence segmentation technique is applied on the processed image which calculates the weighted vectors for the HSOM and FCM which use additional features like entropy and energy and idm. We use fuzzy clustering technique which uses six features and gives the result of the lowest weighted vectors which the image of the tumor in the analysis.

Conclusions:

There are various methods for obtaining the pictures of the tissues but they do not give the exact detail of the infected tissue. Here we apply the clustering technique which gives the values of the low weighted vectors by which on the detail of the tumor is obtained in the computer aided analysis. By using this technique we can make a detailed diagnosis of the tumor which is helpful for the doctors for treating the infected areas.

Wireless Energy Transmitter with Tariff System ECE and EEE Project Report

For transmitting data to the use we use wired transmission lines which is affected by various factors. The proposed system is based on wireless communication along with a tariff system. This is a microcontroller based design which transmits the data to the consumer and records the amount of data which is used for billing.

For transferring the data between the transmitter and to the consumer we use radio frequency signals. in this paper we will see how the circuit is designed and how the data is transmitted to different users.

Brief on working:

In this design we find a transmitter section present at the administrator and individual receivers are provided to the consumers. We use frequency shift keying technique which can abruptly change the carrier signal based on the phase keying.

By using this we can transmit to users with different frequencies on a specified bandwidth. We use a FSK modulator in the transmitter for modulating the carrier signal and it is transmitted by RF transmitter.

The transmitted signal is received at the receiver antenna and it is demodulated by a FSK demodulator present in the receiver device. An 89C51 microcontroller is used which has a 40 pin package which is used for monitoring the components by giving respective signals.

The microcontroller is connected to the PC by using a RS232 cable which converts the serial data into digital data. In the PC the data which is transmitted to each user is stored. We use an LCD in the transmitter section which displays the information on the signals which are sent.

Conclusions:

This is most efficient method for transmitting data to the users when compared to that of conventional wired transmission line method. We can transmit data to the users even when there is heavy rainfall or fog, but in wired methods the signal gets weak when rainfall occurs.

It is very difficult to find the problems occurred in wired lines whereas in wireless method we don’t get problems and if they occur they can be easily modified by checking the transmitter section.
