  • illumination
  • On the purpose of the better visibility and understanding for low illumination images, the proposed method improved the homogeneity measurement with fuzzy entropy and fractal dimension, in order to select the reasonable pixels in the pending sub-region and reduce noises as possibly. (springer.com)
  • The plug-in corrects exposure problems in images with backlit subjects and uneven flash illumination, as well as partial shade. (dpreview.com)
  • In general, the distribution of color values in an image depends on the illumination, which may vary depending on lighting conditions, cameras, and other factors. (wikipedia.org)
  • Since illumination and reflectance combine multiplicatively, the components are made additive by taking the logarithm of the image intensity, so that these multiplicative components of the image can be separated linearly in the frequency domain. (wikipedia.org)
  • To make the illumination of an image more even, the high-frequency components are increased and low-frequency components are decreased, because the high-frequency components are assumed to represent mostly the reflectance in the scene (the amount of light reflected off the object in the scene), whereas the low-frequency components are assumed to represent mostly the illumination in the scene. (wikipedia.org)
  • m ( x , y ) = i ( x , y ) ∙ r ( x , y ) {\displaystyle m(x,y)=i(x,y)\bullet r(x,y)} Where, m = image, i = illumination, r = reflectance We have to transform the equation into frequency domain in order to apply high pass filter. (wikipedia.org)

  • pixels
  • Align channels to correct for for chromatic aberration or pixel offset parallax (image sensor color channels have a vertical offset, so pixels on one edge of sensor will have colors shifted relative to the pixels on the opposite side of the sensor). (noah.org)
  • There are two forms of non-adaptive speckle filtering: one based on the mean and one based upon the median (within a given rectangular area of pixels in the image). (wikipedia.org)
  • More specifically, the side effect can be that pixels become divergent and not reflect the actual color value of the image. (wikipedia.org)
  • At the same time, image processing operations such as selection of ground control points require access to individual data elements (pixels) selected from the more than 30 million available in a typical full-scene image. (wikipedia.org)

(wikipedia.org)
  • Speckle noise in SAR is generally serious, causing difficulties for image interpretation. (wikipedia.org)
