Object Localization with TensorFlow. Add me on LinkedIn if you have any questions and subscribe … 1 $\begingroup$ I'm trying to use MobileNets to localize a rectangular object in an image. Custom Metric. It is where a model is able to identify the objects in images. Are there any object that we want to detect in the image? Such simple observation leads to an effective unsupervised object discovery and localization method based on pattern mining techniques, named Object Mining (OM). Localization and object detection is a super active and interesting area of research due to the high emergency of real world applications that require excellent performance in computer vision tasks (self-driving cars, robotics).
