threshhold function的用法和樣例：
例句
- The experiment results show that the denoised image which used the new threshold function has the higher PSNR and better visual quality.
實驗結果表明，利用新閾值函數去噪后的圖像峰值信噪比明顯提高，視覺效果也有較大程度的改善。 - The improved function is applied to noise reduction of wire rope fault signals, and its effect is compared with that of the traditional multiwave threshold function.
將其應用於鋼絲繩缺陷信號的降噪中，與傳統多小波閾值函數的降噪進行了比較。
