Why discrete Fourier transform is used in digital signal processing?
The Discrete Fourier Transform (DFT) is used in digital signal processing to analyze the frequency content of discrete signals. It converts time-domain signals into their frequency-domain representations, enabling the identification of dominant frequencies, filtering, and spectral analysis. By efficiently transforming data, the DFT facilitates various applications, including audio and image processing, communication systems, and data compression. Its computational efficiency is further enhanced by the Fast Fourier Transform (FFT) algorithm, making it practical for real-time processing tasks.
Fundamental components of digital image processing?
The fundamental components of digital image processing are computer-based algorithms. Digital image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing.
What is digital image processing?
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
What are the differences between Image processing and computer vision?
§ Image processing tends to focus on 2D images, how to transform one image to another by pixel-wise operations, such as noise removal, edge detection, etc. whereas computer vision includes 3D analysis from 2D images. § As inferred from above, image processing does not require any assumptions, nor does it produce any interpretations about the image content, whereas computer vision often relies on more or less complex assumptions about the scene depicted in an image. § The output of image processing is another image whereas the output of computer vision is generally information in the form of a decision or data. § Image processing is a subset of computer vision.
Classification or types of image processing?
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)

Cross-power spectrum of two fourier transform images?
It's (I1./I2*)/(|I1./I2*|), where I2* is the complex conjugate of the Fourier transformed Image 2
What is curvelet transform?
multiscale and multidirectional transform just like Fourier and wavelet but more sparse and redundant....useful in representing 2-D discontinuities in image

Why dft is used in asic?
Discrete Fourier Transform (DFT) is often used in ASIC (Application-Specific Integrated Circuit) designs for signal processing tasks like filtering and frequency analysis. DFT can efficiently convert signals between time and frequency domains, enabling ASICs to perform tasks such as audio processing, image processing, and communication. It allows ASICs to process data quickly and accurately for various applications.
What is Spatial domain to the frequency domain transformation?
Spatial domain to frequency domain transformation refers to the process of converting an image from its spatial representation (pixels) to its frequency representation (amplitude and phase of different frequencies). This transformation is commonly done using techniques such as Fourier transform, which helps in analyzing an image in terms of its frequency content rather than spatial information.
