In all our segmentation examples, we have kept the same values of the coefficients that modulate the relative weight of the data fidelity term (𝛽β) and the one associated with the gradient modulus measure (𝛼α) can be optimized to improve the results (but it makes the method less use...

This solution uses three B1 blocs and four B2 blocs. However, it can be very interesting if we want to compute the gradient behind. In addition, this solution does not require as much memory as that required by the first one. If the delay z-1 is implemented with 8-bit register...
gradient_kernel_x = np.array([[-1, 0, 1]]) gradient_kernel_y = np.reshape(gradient_kernel_x, (3,1)) # Gradient calculation gradient_x = cv2.filter2D(image,-1,gradient_kernel_x) gradient_y = cv2.filter2D(image,-1,gradient_kernel_y) ...
The basic form of ReLU is as shown in Eqn (1), and when it is differentiated, it can be expressed as Eqn (2). The rectified linear activation function overcomes the vanishing gradient problem, allowing models to learn faster and perform better....
Gradient-weighted Class Activation Mapping (Grad-CAM) [19] is a powerful and model-agnostic technique in the field of computer vision, which enhances the interpretability of deep neural networks. Grad-CAM provides a way to visualize and localize the regions of an input image, which contribute mo...
There are many estimation methods based on iterative autofocus, such as the common phase gradient autofocus algorithm and other improved methods [11]. It should be pointed out that the convergence and speed of the closed-loop iterative process will directly affect the imaging processing efficiency an...
Finally, they are transformed to YCbCr space, where the Y channel is normalized in gradient domain by a multi-focus fusion method [204], the Cb and Cr channels are fused according to their weight in the three candidate images. To the best of our knowledge, this is the only paper that ...
This allowed for the elimination of all pixels detected by the first calculation (results of node 17) that fell outside the area of interest. Kartezio next selected a Fill Hole filter in order to transform the selected area limits into a solid binary mask. A final step consisted of ...
