Public Member Functions | |
| void | setSize (I width_, I height_) |
| Sets the size of pixels, optionally allocates memory. | |
| void | free (bool freePixels=true) |
| Frees the memory. | |
| void | summers_makeValid () const |
| Just validates both summers (if needed). | |
| void | summers_invalidate () |
| Justs invalidates both summers (to be called after changes in the pixel-matrix). | |
| BSumRes | getSums (const Block &block) const |
| A shortcut for getting sums of a block. | |
| BSumRes | getSums (I x0, I y0, I xend, I yend) const |
| Gets both sums of a nonempty rectangle in pixels, the summer isn't validated. | |
| SumT | getValueSum (I x0, I y0, I xend, I yend) const |
| Gets only the sum of values (not the sum of squares). | |
Public Attributes | |
| I | width |
| The width of pixels. | |
| I | height |
| The height of pixels. | |
| MatrixSlice< PixT > | pixels |
| The matrix of pixels. | |
| BSummer | summer |
| Summer for values and squares of pixels. | |
| bool | sumsValid |
| Indicates whether the summer values are valid. | |
