This project shows Some selected Signal techniques, including Image and Audio processing, Using the Matlab digital Signal Processing and Image Processing toolboxes.
Other useful operations on the Image were tested, including Image cropping, Image resizing, image, histogram equalization and altering Image brightness.
Then the discrete cosine transform compression examined on the Audio Signal at different compression rates: 50%, 75%, 87.5% Part III deals with Image processing; the project shows examples in smoothing, sharpening, and edge detection.
An Audio Signal was read and different types of filters, including low pass filter, high pass filter, stop band filter and band pass filter, were designed and implemented in order to filter the Audio Signal from Some frequency bands.
We will specifically use the Butterworth filter.
There are many different types of filters available for the construction of filters.
Part II examined Audio filtering in the sense of specific frequency suppression and extraction.
Then different types of IIR Butterworth filters were designed and implemented to filter a Signal that has many harmonics components, including low pass filter, high pass filter, stop band filter and band pass filter.
The comparison was made between FIR low pass flter, butterworth filter, Chebycheve Type I low pass filter and Chebycheve Type II low pass filter.
Part I includes design and implementation of different types of filters for filtering Signal that has different sinusoidal frequency components or noise.
The project is divided to 3 parts.
