Is there any way to get a image removed background from sprite in cocos creator??

这有点难了，估计得第三方支持了吧，这已经是图像处理算法范畴了。

Can you share the third party library or image processing algorithms you said??
I want to use ‘removed background function’ in cocos creator.

Sorry, this is beyond my competence, you can ask others

#5

有点难，shader层面可能可以，例如 判断颜色值？discard?

#6

这功能类似photoshop的抠图

#7

Yes right. I want to know how to judge foreground area and background area.
And is there any way to do that by cocos creator?

这个和cocos没关系了，完全是图形算法方面的问题。你可以通过cocos拿到图片的ARGB点阵，然后自己去学一个算法，来进行分辨。然后回来分享给大家。

OK. Thank you. If you get the algorithm to distinguish , share it, please.
