The same image can also be loaded by going to Import | URL in the File menu and copying the earlier URL and pasting it in the field. gif). Just below the title bar is an information strip that shows the key parameters of the image: the size of the image (720x576 pixels), the image type (8 bit) and the file size (405K). The upcoming sections will provide more details on the basics of image types in ImageJ. [ 14 ] Chapter 3 Image types An image is built up using pixels, where each pixel has a value that is encoded by bits.
Select Image | Stacks | Images to Stack from the menu. You will now have a single window where every slice represents one image that you took. 3. Create the noise-reduction image by selecting Image | Stacks | Z Project… from the menu and use Average Intensity as the projection type. A thing to keep in mind is the following: when anything moves between the individual exposures, this method will not provide good results. It is possible to correct for simple shifts, but this only works in the simplest of cases.
Next, we will look at Electronic or Dark noise. [ 29 ] Advanced Image Processing with ImageJ Correcting Shot noise Shot noise is caused by the physical properties of light; light can be seen as packages of light or photons. The number of photons that are collected by each photo-detector site on the camera determines the final pixel intensity. If only a few photons hit the detector at any time, the differences in the number of photons could be large. This is called a Poisson process, and the signal-to-noise ratio can be expressed as follows: SNR = N N This means that the signal-to-noise ratio (SNR) will get larger as the number of photons (N) increases.
