End-To-End Deep Neural Network for Salient Object Detection in Complex Environments
December 15th, 2023
The present protocol describes a novel end-to-end salient object detection algorithm. It leverages deep neural networks to enhance the precision of salient object detection within intricate environmental contexts.
Our research range from salient object detection, computer vision, image processing and more. We want to respond to the application of salient object detection, such as its use in smart grid for inspecting insulators. The next research advancement involves transferring salient object algorithms for learning in the context of smart grids.
The convolutional neural networks can more effectively act as salient information from images, enhancing the processing of salient object detection. Therefore, they advance the research in salient object detection. Our research outcome improves the accuracy of salient object detection, and allow for the transfer of algorithms, such as their application in smart grids for effectively segmenting and detecting insulators.
To begin, load a deep learning library in Python, such as PyTorch. Import torch and torch vision models as models. Next, load the pre-trained VCG16 model.
To generate the pseudo code of the DCL algorithm, provide image dataset SOD into the input field and use trained DCL model as the output field. Now initialize the DCL model with the VGG16 backbone network. Pre-process the image data set, then split the data set into training and validation sets.
Define the loss function for training the DCL model. Set the training hyper parameters as 0.0001 for learning rate, 50 as the number of training epochs set, 8 as the batch size, and adam as the optimizer. Combine the outputs of the DCL and DEDN networks and refine the saliency map using a fully connected conditional random field model.
To process the image, click on the run code to bring up the GUI interface. Now, press open image to choose the selected image for detection. Then press display image to show the selected image.
Click on start detection to detect the selected image. Lastly, press select the save path and choose the appropriate file location to save the image results. The removal of the DCL model from the algorithm caused a decrease in F-beta value and an increase in the EMAE value.
This algorithm only removes the DEDN structure. A similar decrease in the F-beta value and an increase in the EMAE value were observed compared to the complete module. The DCL algorithm described the target boundary when detecting images in the SOD database, but struggle to effectively filter the background.
However, the DEDN algorithm strengthened the target boundary, but suppressed background redundancy information.
