可以使用PyTorch的阈值函数torch.where()来实现。 # 应用阈值threshold=100edge_image=torch.where(edge_strength>threshold,255,0) 1. 2. 3. 现在,你已经成功地实现了Sobel边缘检测器。你可以将edge_image保存为图像文件,或者在Jupyter Notebook中显示它。 # 显示结果importmatplotlib.pyplotasplt plt.imshow(edge_...

,我曾經討論過用Verilog實現Sobel edge dector的原理與方式,用的是DE2-70,但DE2畢竟是大家最熟悉,也最流行的平台,所以這次來看看如何在DE2實現Sobel edge detector。 在DE2平台所需做的修改 我以DE2 CD的DE2_CCD範例為藍本,使用130萬像素的TRDB-DC2為輸入,VGA為輸出,將Sobel edge detector加到DE2上。Sobel....

Edge detection operation is an essential part in the field of image processing. There are many methods to detect edge, but most of them are implemented by software which the data processing is slow and the calculation is complex .There are still some hardware-based implementation which however ...
This paper presents a comprehensive review and a comparative study of various hardware/FPGA implementations of Sobel edge detector and explored different architectures for Sobel gradient computation unit in order to show the various trade-offs involved in choosing one over another. The different ...
