INTERFACING TRAFFIC LIGHT CONTROLLER

To interface a traffic light controller with microprocessor 8085 and to control the flow of traffic at a four-way junction.

APPARATUS REQUIRED: Microprocessor kit 8085 +5V supply Traffic Light Controller Interfacing Kit. INTRODUCTION: The board is a simple contraption of a traffic control system wherein the signalling lights are simulated by the blinking ON-OFF control of light emitting diodes. The signalling lights for the pedestrian crossing are simulated by the ON-OFF control of dual colour light emitting diodes. A model of four road lane junction, the board has green, yellow and red LED which are the green, orange and red signals of the actual system. Twenty LEDs are used on the board. In addition, eight dual colour LEDs are used which can be made to change either to red or to green. CIRCUIT DESCRIPTION: The control of the LED is as follows: The board communicates with the microprocessor trainer by means of a 26 core cable which is connected to the output of any parallel port of V1 range of trainers The outputs are the input to buffers 7406 whose outputs drive LEDs. The buffered output applied to the anode of the LEDs decides whether it is ON or OFF. The figure below shows the LED positions and the port lines which control the LED.

At the end of the lab session, students will have the information’s on image, digital image, and the processing techniques. Image An image may be defined as a two dimensional function f(x,y), where ‘x’ and ‘y’ are spatial coordinates, and the amplitude of ‘f’ at any pair of coordinates x,y is called intensity or gray level of the image at that point. DIGITAL IMAGE: ‘x’, ’y’ and the amplitude ‘f’ are all finite and discrete quantities means then the image is called as digital image. DIGITAL IMAGE PROCESSING: The field of digital image processing refers to processing of digital images by a digital computer. Each object has finite number of pixels or pels or image elements or picture elements. IMAGE RESOLUTION: Image resolution is defined as the number of pixels that can be accommodated in a unit area. Image resolution depends on number of values for N and number of bits used in a gray level (m). If N and ‘m’ is high, then the resolution will be more. HUE:

Hue is an attribute associated with the dominant wavelength in a mixture of light waves. Thus hue represents dominant color as perceived by an observer eg., red, yellow. Saturatio It refers to relative purity or the amount of white light mixed with the hue. The pure spectrum colors are fully saturated (RGB).Color such as pink and lavender are less saturated. ie., The degree of saturation being inversely proportional to the amount of white light added. Hue and saturation taken together are called chromoticity. IMAGE HISTOGRAM: An image histogram is a type of histogram that acts as a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value. The left side of the horizontal axis represents the black and dark areas, the middle represents medium grey and the right hand side represents light and pure white areas. The Vertical axis represents the size of the area that is captured in each one of these zones. The histogram for the very dark image will have the majority of its data points on the left side and centre of the graph. The histogram for the very bright image with few dark areas is shadows will have most of its data points on the right side and the centre of the graphs. FFT TRANSFORM: Typically, 2-D-Fourier transform (2-D-FT) is used as the representation of complex SAR images. However, the energy of the coefficients of 2-D FT on the complex SAR image

distributes in the whole frequency domain. Generally, the frequency signals are divided into real and imaginary parts, and quantized with Lloyd-Max quantizer However, the compression ratios of the frequency domain compression algorithms are almost limited in 10.4:1o r 9.8:1, which are not very high. Wavelet transform can locally analyze time and frequency in multiscale and shows very strong decorrelation ability. As it is particularly suitable for nonstationary signal processing, wavelet transform has been applied to complex SAR image compression currently; most compression algorithms of complex SAR image adopt the traditional wavelet transform. However, for the complex SAR images, which are rich in edges and texture, traditional wavelet transform does not show efficient representation. proposed an algorithm which extracted edges of SAR image with wedge let transform and encoded the edges and texture separately. used 2-D oriented wavelet transform for remote sensing compression. The SAR images used in are not complex SAR images. To the best of our knowledge, directional wavelet transform has not be applied to the compression of complex SAR images. Directional wavelet transform achieves the direction extraction while keeping the property of multiscale analysis of discrete wavelet transform (DWT). Directional wavelet transform can be divided into two classes: Frequency-domain transform and spatial-domain transform. The frequency-domain directional wavelet transform, such as contour let which continuously performs directional filter on the high-frequency sub bands of wavelet transform, gives an efficient representation of the edges at the cost of high redundancy. The spatial-domain directional wavelet, such as directional lifting wavelet transform (DLWT), employs direction prediction for wavelet decomposition, which adapts the wavelet transform direction to the image edges. DLWT integrates spatial direction prediction into the wavelet transform lifting framework, provides an efficient representation of edges along multiple directions of images, and thus reduces the energy of high-frequency bands and achieves more energy clustering. As the real parts and imaginary parts of complex SAR image as well as the real image of fast FT (FFT) are rich in edges, two complex SAR image coding schemes using DLWT are proposed. Fourier Transform (FT) with its fast algorithms (FFT) is an important tool for analysis and processing of many natural signals. FT has certain limitations to characterise many natural signals, which are nonstationary (e.g. speech). Wavelet compression system consists of several components:1) filters and algorithms for performing wavelet decomposition and reconstruction, 2) a bit allocation strategy, and 3) quantizers. In order to minimize algorithm complexity and to reduce susceptibility to channel errors, the quantizer output is not encoded with an entropy or arithmetic coder. Side information concerning normalization and bit allocation can be coded in only a few bits for an entire image. The wavelet transform is a relatively new technique for decomposition of a data set with orthogonal (ornonorthogonal) basis functions and is becoming widely used in image compression. The orthogonal wavelet decomposition provides a multi resolution representation of a signal over an orthonormal basis. It offers several advantages for SAR data compression:

1. The decomposition of an image into a representation selective both in frequency and spatial orientation allows allocation of quantization bits to "important" components. 2. Algorithms for performing a wavelet decomposition and reconstruction are recursive, computationally efficient, and easily implemented in hardware. The computation of a wavelet transform, as described by Mallat, has a computational burden on the order of & V' Fast wavelet transform algorithms can reduce the computational burden 3. The decomposition of an image into a pyramid of detail images results in a set of coefficients that have reduced dynamic range compared to the original image. This is particularly important for compression of SAR imagery due to its very large dynamic range. 4. A wavelet multiscale decomposition of an image is convenient for progressive image transmission. A coarse resolution image can be selected from a sensor or database, and then a) browsed at coarse resolution for data quality, data validation, correct location, etc. and or processed by algorithms which require only coarse resolution input data, or b) a subset of the image can be transmitted and displayed at the finest available resolution.
