20.06.2020 · This time, we are using PyTorch to train a custom Mask-RCNN. And we are using a different dataset which has mask images (.png files) as . So, we can practice our skills in dealing with different data types. Without any futher ado, let's get into it. We are using the Pedestrian Detection and Segmentation Dataset from Penn-Fudan Database.
We have used PyTorch detection model maskrcnn_50_fpn model in PyTorch and in PyTorch lightning to perform instance segmentation of Weapon&Knife with Same data, ...

21.05.2021 · Pytorch + Pytorch Lightning = Super Powers. Welcome to this beginner friendly guide to object detection using EfficientDet.Similarly to what I have done in the NLP guide (check it here if you haven’t yet already), there will be a mix of theory, practice, and an application to the global wheat competition dataset.. This will be a very long notebook, so use the following table …
01.06.2020 · Fine-tune Mask-RCNN on a Custom Dataset¶. In an earlier post, we've seen how to use a pretrained Mask-RCNN model using PyTorch.Although it is quite useful in some cases, we sometimes or our desired applications only needs to segment an specific class of object which may not exist in the COCO categories.
The input to the model is expected to be a list of tensors, each of shape `` [C, H, W]``, one for each image, and should be in ``0-1`` range. Different images can have different sizes. The behavior of the model changes depending if it is in training or evaluation mode. During training, the model expects both the input tensors, as well as a ...
