In signal processing noise can be considered random unwanted data without meaning.
× 282
the number of cycles (of the signal) per second.
× 273
covers signal processing where input is an image, such as a photograph or video frame and the output could be an improved or altered image, parameters related to the image or information abou…

× 244
a mapping between a finite set of discrete points in the frequency and time domains. DFT requires an input function which is discrete and non-zero, such as a s…

a method expressed in a finite list of steps of well-defined instructions to process a signal.
× 202
an electronic filter that passes low-frequency signals but attenuates signals with frequencies higher than the cutoff frequency.

image-segmentation refers to the process of partitioning a digital image into multiple segments, typically to locate objects and boundaries.
× 177
a high-level interpreted general programming language. Python has popular numerical and scientific libraries/packages, most notably numpy and scipy. The scipy.signal package is a powerful …
