Couple things to show you ,first let me just show you this kind of works. Allright, heres some optic flow results taken from a computer vision class 2003 from a actually its a tutorial. Here listed on the bottom and you can see that when you run loops at the, on that front tree without kermits, you get sort of terrible results and while when you run it with the pyramid you get a much better result. And our goal is to really get that much better result. But before we can do this we have to talk a little bit more about multiple scale. So we been having all this multiple scale stuff. Now this isnt going to surprise you that it relates to some of the aliasing stuff and frequency stuff that we talked about, oh God, sounds like, found, feels like months ago. Its probably months ago. I have no idea when it was. Anyway when we were talking about Fourier analysis in different scale. And what were going to do now is take a little detour through multi scale and then well come back to Lucas

What is ideal sampling in image processing?

Ideal sampling (Ideal means necessary to capture all the information). As the Point Spread Function (PSF) is the basic brick of which the images are built, one should record details at least on the scale of the PSF to gather all the available information.

How is image sampling done?

Since an analogue image is continuous not just in its co-ordinates (x axis), but also in its amplitude (y axis), so the part that deals with the digitizing of co-ordinates is known as sampling. In digitizing sampling is done on independent variable. In case of equation y = sin(x), it is done on x variable.

What is a sample in an image?

1.7, a sampled image is an array of sampled image values that are usually arranged in a row-column format. Each of the indexed array elements is often called a picture element, or pixel for short. The term pel has also been used, but has faded in usage probably since it is less descriptive and not as catchy.

What is sampling process in image processing?

Since an image is continuous not just in its co-ordinates (x axis), but also in its amplitude (y axis), so the part that deals with the digitizing of co-ordinates is known as sampling. And the part that deals with digitizing the amplitude is known as quantization.

What is sampling resolution in image?

The spatial resolution of a digital image is determined by the distance between pixels, known as the sampling interval, and the accuracy of the digitizing device. The numerical value of each pixel in the digital image represents the intensity of the optical image averaged over the sampling interval.

Does sampling affect the number of pixels?

Sampling leads to digitization of the coordinate values in a signal/image. Sampling affects the resolution of an image in terms of the number of pixels in x and y directions in the image. Quantization is the number of distinct grayscale/color levels achieved by digitizing the amplitude values in the signal/image.

How does increasing the sampling rate of a digital image affect image quality?

In digital imaging, increasing the sampling rate is equivalent to increasing the image resolution.

How does sampling affect the quality of an image?

By image sampling, it can drastically affect the perceived resolution of them by both increasing and decreasing their visual quality. If done properly with higher quality images, samples can easily be enlarged beyond their original resolution without losing much detail or sharpness.

What is the effect of sampling on an image?

The sampling rate determines the spatial resolution of the digitized image, while the quantization level determines the number of grey levels in the digitized image. A magnitude of the sampled image is expressed as a digital value in image processing.
