How does Mask R-CNN automatically output a different number of objects on the image?
Recently, I was reading Pytorch's official tutorial about Mask R-CNN.
When I run the code on colab, it turned out that it automatically outputs a different number of channels during prediction. If the ...

How would one modify the Mask-RCNN head for polyline detection?
In Mask-RCNN they modify the standard mask head for human pose keypoint detection with the following tweaks:
Each keypoint is a 1-hot mask
Instead of sigmoid non-linearity on the output of the final ...

Improving Mask RCNN by arbitrary scaling head input
Currently, I am looking at how Mask R-CNN works. It has a backbone, RPN, heads, etc. The backbone is used for creating the feature maps, which are then passed to the RPN to create proposals. Those ...

Getting bounding box/boundaries from segmentations in UNet Nuclei Segmentation
From my understanding, in a tissue where nuclei are present and need to be detected, we need to predict bounding boxes (either rectangular/circular or in the shape of the nucleus, i.e. as in instance ...

How much should we augment our training data?
I am wondering how much I should extend my training set with data augmentation. Is there somewhere a pre-defined number I can go with?
Suppose I have 10000 images, can I go as far as 10x or 20x times, ...

How can I decrease the time to compute the mask in the Mask-RCNN for human body detection?
I am using Mask-RCNN to detect human bodies in photos, to get a rough approximation of the ratio of their heights to the length of their chests. I want to decrease the time for making the mask of the ...

Is Mask R-CNN suited to solve a multi-class classification problem where the classes are related?
I want to create a model to solve a multi-class classification problem.
Here are more details about my problem.
Every picture contains only one object
The background is very simple
All objects ...
