28.03.2019 · iou = get_iou (masks, predictions) mean_iou_loss = tf.Variable (initial_value=-tf.log (tf.reduce_sum (iou)), name='loss', trainable=True) train_op = tf.train.AdamOptimizer (0.001).minimize (mean_iou_loss)

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 ...

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.

Divising a pixelwise loss function, such that a deep network performs segmentation, with the mindset of classification and cross-entropy, we get something ...

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

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.

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 ...

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?

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.

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