Density based traffic signal system using image processing

Contact Me for Project Prize Mail Id:  tamilblogelectronic@gmail.com Measure Traffic density and ambulance detection in Realtime project. What We Do in This Project: (Both Software & Hardware Project Available) ( i) Traffic Density Measure - Realtime (Means using Traffic Camera or Traffic Video) First,  we do Vehicle Detection in Video/Camera using Image Processing. Second, we Count the Vehicle We Detected in Video/Camera using Image Processing. Third, We Compare Two lane Vehicle Density in Video/Camera , if lane detect more no. of vehicle will be Prioritized first.   (ii) Ambulance Detection in Single Lane  - Realtime (Means using Traffic Camera or Traffic Video) : First, We Collect the Images of Ambulance. Second, we train our Image model using sample ambulance image. using Yolo image Model, we able to Detect the Ambulance in Video/ Camera. (iii) Ambulance Detection in Multiple Lane  - Realtime (Means using Traffic Camera or Traffic Vid...

What is Noise Filter?

Noise Filter is a filter Which Remove unwanted Noise.

In Other words Noise cancelling means cancelling Noise in Particular frequency range.


How Filters Used To Cancel Noise ?


Noise-cancelling headphones cancel sounds using Noise cancelling filter in other words noise cancelling means cancelling particular frequency range


you see Human speaks range is 125 Hz to 8 kHz.


and Human hearing range you know that 20 Hz to 20,000 Hz


I will give you perfect example that


If you recording or speaking to someone in mobile in traffic your range of frequency will be 125 Hz to 8 kHz.


avg. traffic frequency range is above 1000 Hz


If we accurately measuring or considering means human speaking in mobile freq range is 300 to 3400 Hz.


as you see you will normally speak in mobile is 500 Hz to 900 Hz


now noise cancel filter will cut above and below 500 Hz to 900 Hz because you to remove traffic noise which is above or exact 1000 Hz .


So noise cancelling filter is a frequency canceler particular frequency range


this one simple example to understand how noise-cancelling filter works


In Complex example your both message or voice you need to hear and noise will be more or less in same range and mix well


generally active noise filter will use for noise cancelling

fir filter advantages and disadvantages

 What is FIR Filters? The filters designed by using finite number of samples of impulse response are called FIR filters. These finite number of samples are obtained from the infinite duration desired impulse response h (n). Here h (n) is the inverse fourier transform of H (O), where H (0) is the ideal (desired) frequency response. The various methods of designing FIR filters It differs only in the method of determining the samples of h(n) from the samples of h (n). The various steps in designing FIR filter are i) Choose an ideal (desired) frequency response, H.(w). ii) Take inverse fourier transform of H (w) to get h,(n) or sample H, (o) at finitenumber of points (N-point) to get Ĥ(k). iii) If h (n) is determined, then convert the infinite duration h (n) to a finite duration h(n). (usually h(n) is an N-point sequence) or If ħ(k)is determined then take Npoint inverse DFT to get h(n). iv) Take Z-transform of h(n) to get H(z), where H(z) is the transfer function of the digital filter...
