| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| eps | Tolerance value. | |
| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| roiSize | Specifies the height and width of an ROI. | |
| srcStep | Source buffer step size (width of the buffer in bytes). | |
| value | Specified value. | |
| value[3] | An array of three specified values. | |
| value[4] | An array of four specified values. |
These functions step through an ROI in a source buffer and compare the source floating-point data for equality within a specified tolerance.
When the difference between the floating-point value and the constant is less than or equal to the specified tolerance, the output data is set to all ones.
When the difference between the floating-point value and the constant is greater than the specified tolerance, the output data is set to all zeroes.
Output data is written to a 1-channel Fw8u destination buffer.
