[−][src]Module imageproc::integral_image
Functions for computing integral images and running sums of rows and columns.
Traits
ArrayData | Hack to get around lack of const generics. See comment on |
Functions
column_running_sum | Computes the running sum of one column of image, padded at the top and bottom. The padding is by continuity. Takes a reference to buffer so that this can be reused for all columns in an image. |
integral_image | Computes the 2d running sum of an image. Channels are summed independently. |
integral_squared_image | Computes the 2d running sum of the squares of the intensities in an image. Channels are summed independently. |
row_running_sum | Computes the running sum of one row of image, padded at the beginning and end. The padding is by continuity. Takes a reference to buffer so that this can be reused for all rows in an image. |
sum_image_pixels | Sums the pixels in positions [left, right] * [top, bottom] in F, where |
variance | Computes the variance of [left, right] * [top, bottom] in F, where |
