根据我的尝试,这个插件里的alpha遮罩功能,确实能够解决一定的边缘不自然问题,但没有看到相关模型的下载,所以应该是直接用传统机器学习方法去实现的。 所以,它这个alpha遮罩的精度也是一般的,如果遇到不好抠的图像,还是直接去外部抠图网站省事,或者用自己训练过的模型搞。 不管怎么样,rembg也是方便实用的小工具了,辅助一...
贝叶斯算法基于图像局部颜色一致性的假设前提,封闭式抠图预先假设了颜色线性模型,这两种经典方法都预先假设了颜色分布模型,考虑到颜色分布不一定服从一个确定的模型,2009年有学者提出了基于学习的抠图算法(learning based matting)[4],将抠图问题视为一个半监督的学习问题,以更通用的学习的方法拟合颜色模型求解α值,并且...
把digital matting技术应用于图像，是基于这样一个概念，它认为一幅图像是由背景和前景合成的，只是在不同的区域两者参与的比例不一样，在只有背景的地方，前景的参与比例为0％；而在只有前景的地方，背景的参与比例为0％。因此我们把这个比例值定义为一个未知数alpha，即α。这样我们把图像C分割成一个...
