Abstract
Method of controlling the resolution of a hyperspectral image from an image sensor comprising pixels and at least one filter that defines subpixels within each pixel includes defining a window on the image sensor with an array of rows and columns of subpixels; weighting the subpixels within the window based upon one or more predefined parameters of the hyperspectral image to establish a value for a weighted average for the array for the predefined parameters; shifting the window by a predefined number of rows or columns; repeating the weighting and shifting steps for all possible windows on the image sensor; and processing the hyperspectral image based on the weighted averages.
Claims7
A method of controlling the resolution of a hyperspectral image from an image sensor comprising pixels and at least one filter that defines subpixels within each pixel, the method comprising:
- defining a window on the image sensor comprising an array of rows and columns of subpixels,
- weighting the subpixels within the window based upon at least one predefined parameter of the hyperspectral image to establish a value for a weighted average for the array for the at least one predefined parameter,
- shifting the window by a predefined number of rows or columns wherein the predefined number is less than the number of respective rows or columns of subpixels in a pixel,
- repeating the weighting and shifting steps for all possible arrays on the image sensor, and
- processing the hyperspectral image based on the weighted averages.
