locate nearest value in lookup table
Hi everyone,
I have a pile of data derived from an analytical device, which reports
values as a continuous distribution. I need to associate classes
(based on the Munsell color system) using a standard look-up table -
the problem is that I would like to find the *closest* matching entry
in the lookup table.
I have attempted to do this by first creating as difference vector
between color space

...#39;ll want something like:
(opus_int16)((unsigned)demixing_matrix[2*i+1] << 8)
(though you might want to check it too)
2) In mapping_matrix_multiply_short(), I would recommend something along
these lines (untested) to improve accuracy:
opus_int32 tmp = 0;
for (col = 0; col < input_rows; col++)
{
tmp +=
(matrix_data[MATRIX_INDEX(matrix->rows, row, col)] *
input[MATRIX_INDEX(input_rows, col, i)]) >> 8;
}
output[MATRIX_INDEX(output_rows, row, i)] = (tmp+64)>>7;
3) Looking at your get_*() function to compute offsets, I thi...
