Device pointer interface: Image Histogram |
- Parameters:
-
| [out] | d_hist | Count of occurances - PxN matrix |
| [in] | length | Length of input matrix d_data - N |
| [in] | d_data | Device-side vector or matrix - MxN |
| [in] | nbins | Number of bins in h_bins - P |
| [in] | h_bins | Host-side vector indicating center of each bin (can be NULL) |
| [in] | nsets | Number of rows in input data - M |
| [in] | ngfor | Number of gfor passes |
| [in] | min | Minimum binned value (eg. 0) |
| [in] | max | Maximum binned value (eg. 255) |
- Note:
d_hist is: a 1xP vector hist for vector inputs, or a PxN matrix hist for MxN matirx inputs
