WebAnswering Jessica's question directly - one reason for downsampling is when you're working with a large dataset and facing memory limits on your computer or simply want to reduce processing time. Downsampling (i.e., taking a random sample without replacement) from the negative cases reduces the dataset to a more manageable size. WebJun 17, 2014 · Downsampling is a kind of sample rate conversion that is dividing frequency. Sometimes, it's a decimation of samples. Sometimes, it's a decimation of samples. Read …
WebJun 19, 2024 · Thus the filter's radial influence seems appropriate when choosing every 4th value when downsampling. So my intuitive rule of thumb is $\sigma = 1/(2s).$ Following this, ... but it is a usable definition. By this definition, we need to set $\sigma=1/s$. This definition avoids visible aliasing artefacts, but it also blurs the image too much. ...
