15.08.2019 · In this work, IoU-balanced loss functions that consist of IoU-balanced classification loss and IoU-balanced localization loss are proposed to solve the above problems. The IoU-balanced classification loss pays more attention to positive examples with high IoU and can enhance the correlation between classification and localization tasks.

23.05.2020 · IoU loss function is a bounding box regression function that is scale-invariant.An improvement from the l2-norm loss function. Fig: 0 It was perfect for overlapping boxes but suffered vanishing ...

Improvement of the Object Detection after using GIoU loss function (source). In the object detection task, the most common evaluation metric is IoU, ...

Nov 07, 2016 · Update July 2021: Added section on alternative Intersection over Union implementations, including IoU methods that can be used as loss functions when training deep neural network object detectors. Looking for the source code to this post?

In this work, we propose IoU-balanced loss functions which consist of IoU- balanced classification loss and IoU-balanced localization loss to ...

Generalized IoU(GIoU) Loss ... GIoU loss maximizes the overlap area of the ground truth and predicted bounding box. It increases the predicted ...

07.11.2016 · Just as you train a neural network to minimize mean squared error, cross-entropy, etc., this method acts as a drop-in replacement loss function, potentially leading to higher object detection accuracy. A PyTorch implementation of IoU (which I have not tested or used), but seems to be helpful to the PyTorch community.

May 23, 2020 · IoU loss function is a bounding box regression function that is scale-invariant.An improvement from the l2-norm loss function. Fig: 0 It was perfect for overlapping boxes but suffered vanishing ...

a loss function. The comparison between IoU loss and Binary Cross Entropy loss is made by testing two deep neural network models on multiple datasets and ...

I always use mean IOU for training a segmentation model. More exactly, -log(MIOU). Plain -MIOU as a loss function will easily trap your ...

Object detection neural networks commonly use $\ell_1$-norm or $\ell_2$-norm for their cost function (aka. loss function). Our work shows that there is not a strong correlation between minimizing these commonly used losses and improving their IoU value.

Aug 15, 2019 · IoU-balanced Loss Functions for Single-stage Object Detection. Single-stage object detectors have been widely applied in computer vision applications due to their high efficiency. However, we find that the loss functions adopted by single-stage object detectors hurt the localization accuracy seriously. Firstly, the standard cross-entropy loss ...
