In image processing , the primary purpose of convolution is to extract features from the input image. A convolution between a kernel (a small matrix, also called convolution matrix, or mask) and an image can be used for blurring, sharpening, embossing, edge detection, and more. The ...

According to whether the current position is masked in the input image, gated convolution automatically learns the mask from the data, thereby saving more effective information. Table 3.

Therefore, The Fourier method has a disadvantage in that it is not suitable for a miniaturized integrated system because it uses the existing complex and bulky optical elements. Additionally, arbitrary convolution processing requires not...

常用的 mask 有 Prewitt 算子,Sobel 算子,Laplacian 算子 Prewitt 算子和Sobel 算子都是通过求一阶导数来计算梯度的,用于线的检测,通常用于边缘检测。在图像处理过程中,除了检测线,有时候也需要检测特殊点,这就需要用二阶导数进行检测,著名的就是拉普拉斯(Laplacian)算子。 对图像求两次导数,公式如下: \nabla^{2}...
Subsequently, a novel framework called Scale Normalization for Image Pyramids (SNIP) was presented, which involved training several detectors, with each detector assigned to specific scale images. Wang et al.39 proposed a cascaded mask generation framework to effectively combine multi-scale inputs and...
