key fruit meaning in Chinese

【植物；植物学】翅果〔如枫树、榆树等果实〕。

The key fruits is as follows : 1 in the image - preprocessing , the optimal edge - extraction algorithm was used to increase the correlation s / n and auto - thresholding technique was introduced to decrease the affection of illumination distortion on the recognition possibility , and the bottle - neck of image - preprocessing was delivered to the dsp which is on the genesis card instead of cpu
论文的重点内容如下： 1 、在预处理图像中，优选了边缘检测算法，并引入自动门限，还将预处理的速度瓶颈交给了图像卡上的dsp ，这样不仅提高了s n ，而且也提高了对不同光强的适应能力，还防止了速度瓶颈、减轻了cpu的负担。
