You can fine-tune geospatial foundation models, such as Prithvi and ClimaX, using the Train Deep Learning Model tool in the Image Analyst toolbox. Prithvi, developed by NASA and IBM, is trained on Harmonized Landsat & Sentinel (HLS) data and supports 30-meter global land observations. It can...
Speckle Smooths or removes speckles in radar imagery using a noise model. Spectral Conversion Applies a matrix to a multiband image to affect the spectral values of the output. This can be used to convert a false-color image to a pseudocolor image. Statistics Calculat...
Stray light is the unintended, unwanted light that interferes with sensors in an optical system. Think of the sunbursts that speckle outdoor photos or the extra set of floating candles that appear in birthday cake videos. Any unplanned light that reaches the final image is considered stray ...
Similar activi- ties can induce very different patterns in different rooms. As the person is small compared to the room dimensions, their contribution is extremely small as compared to the ambi- ent light hitting the wall – often below 1% of the maximum pixel intensity and below the no...
Image from File with Bit Depth of 2 Notice that we have gained some detail, but that the image is still very choppy. In the histogram for this image, below, we see huge gaps between the tones, confirming the choppiness or posterization. (The histogram is a graph of the tones in an im...
at night using the Canon EOS-20D. While the print of the image is too small and hides most of the noise, a closer look at a small section reveals two “stars,” which are actually hot pixels. Using the method described above, the dark current of these hot pixels was correctly indent...

(PS) in a temporal sequence of interferograms. Among the factors that could limit the effectiveness of this monitoring technique, there are spatial decorrelation and temporal decorrelation, but, in an urban environment, such as the study area of the present work, there is an abundance of (PS)...
