Hi Everyone, I hope you enjoyed this tutorial.
If you want to Train your Custom Mask-RCNN detector, I made a tutorial about that as well. You can find it here: th-cam.com/video/WuvY0wJDl0k/w-d-xo.html
Your lessons are always clear. You are doing a great job
Thanks for sharing! My master paper is about the Instance Segmentation, This video is very important for me!
Thnx a lot for an amazing video.
A video session for training custom objects would be highly appreciated :)
Same request
Hi Sofian, here I've just released a video about that th-cam.com/video/WuvY0wJDl0k/w-d-xo.html
I became a big fan for your videos
Thank you for such awesome tutorial!
Sir you are great in all your lecturers... Please do you have website we do you always get images and videos for your lecture... Please kindly share the website so that can be getting our images and videos to test those programs as well
thanks for your help. Is it possible to crop the image corresponding to the mask ???
Thank you a lot for that video sir, i just want to ask you how to define the name of the objects in the image.
thank you for advance
Is there any way to add image category in output image?
great video sir. this help me alot. i have some question and hope u will help me to find the solution. so i have a image data collection in which i want to extract (segmentation of a object)a particular object in all images with the help on mask r cnn and raspberry in realtime..plz help me
Thank you for the video!
I didn't get why the box and the mask didn't match by width and height? I think that box is the boundary rectangle of the mask. This is not true? When we draw the mask we can see that it less than the rectangle.
You need to consider that in deep learning the image is never processes at its original size, but it is shrinked to a square of a predefined size by the deep learning model.
So once we extract the information of detections and masks, is necessary to resize them considering the proportions and size of the original image.
Great video. can we segment the region of interest based on the calculated mask?
Hey nice video , could you please say what if I want to segment X ray images . How will I proceed with this algorithm ?
Please explain the cases in which we cannot load the file from the source u have provided on the website.
Thank you!
Hi again Sergio,
Nice tutorial mate! I have a custom annotated.json file and i want to train a dataset. Unfortunately i couldn't understand how to get frozen_inference_graph and mask_inception.Is it based on tfrecord file? I am new in ML and this is something that is not clear for me.
hi Somu, I did a video about Training mask rcnn just a week ago. you can check it here th-cam.com/video/WuvY0wJDl0k/w-d-xo.html
Hello somu, I m going through the same problem, I want to edit those file ie frozen and mask inception for my custom object so that I can segment it.. please can u help me to do this task ..thanks in advance
Can I learn pedestrian route trajectory from the gods, great!
Hi bro, how can we obtain frozen_inference_graph_coco.pb and mask_rcnn_inception_v2....... & can u show us custom data for this
Respected Saragivo,
Wonderful Video, I want to request you just one.
How we can add our own objects if not included in 80 classes?
Secondly, you did not labeled the objects.
Thanks,
Regards
Khan, from Bolzano, Italy
you'll find here a video that explains how to train Mask rcnn to detect custom objects: th-cam.com/video/WuvY0wJDl0k/w-d-xo.html
@@pysource-com I have watched both videos. But I'm not sure how to replace my own customer model and config files to do the segmentation. To explain further, this video calls for a frozen/infernece/graph_coco and the mask_rcnn_inception file
But I didn't follow where we create those files in the custom object detection video.
Thanks in advance for your help
Opencv is Open Curiculur Vitae
Thanks Professor
Very good instructional video. Using this method is there a way to detect and segment landscape features such as grass?
Yes it's possible to do that by training a custom model
@@pysource-com Maybe you would consider doing a tutorial on creating a custom model.
brother please make a video , point cloud compression or point cloud segmentation, point cloud object detection for autonomous driving ................please
I am using mask rcnn for detection and classification of images (150) and 2 classes, While training for 10 epochs I am getting worst detection (detecting empty blocks) and accuracy (map = .003), any suggestions?
How many epochs required to get decent segmentation?
What version of opencv did you use? I get error : "Requested blob not found in function 'getBlob'
try installing latest version of opencv contrib, it should work
pip install opencv-contrib-python
How to get the class name over the image!?
Is it possible to calculate the area of this masks? By the way.... Nice video 😊
yes, you can do that just after you get the mask.
The mask is represented as white area on black bacgrkound.
So you caount the white pixels and you get the area.
area = cv2.countNonZero(mask)
Thank you for the tutorial
Do u have a telegram channel ?
can I learn how to convert the Mask RCNN custom datassets trained file (h5) to pb and pbtxt in your course?
Nope. There are not codes out there which will allow you to do this. But you can simply load the h5 file with keras and get the exact same info in realtime: bounding boxes, scores, masks and classes
permisiion to learn srir, thank you
how to replace any detected mask with any other image.
SO link is given below!!!
please make a video with custom object by train model and detect realtime on webcam or on video
I've got that already: th-cam.com/video/WuvY0wJDl0k/w-d-xo.html
good work , how can i load those two files? mask and weight
below the video there is the link to the blog, where you can download the entire source code with these files included
hi, the link to download the files does not work.
Hi, it seems there is some problem with the server and we're working on fixing it. please try later
please, I got the following error when I tried to import my own model?

mask = masks[i, int(class_id)]

why this error?
