Optimizing ZNCC calculation in binocular stereo matching

作者：

Highlights：

• Method for reliable computation of similarity measure is proposed.

• Zero-mean normalized cross-correlation is optimized to four efficient factors.

• Storage strategy is proposed to store calculation templates by column.

• Circular-queue data structure is applied to the matching process.

• Results reveal remarkably shorter execution time on a 2.6 GHz computer.
