CNN Example Architectures
This is a very high level view of practical structures of CNNs before the advent of more innovative architectures such as ResNets.
CNN Layers
In the convolutional layer the first operation a 3D image with its two spatial dimensions and its third dimension due to the primary colors, typically Red Green and Blue is…
Fast and Faster RCNN Object Detection
Fast-RCNN is the second generation RCNN that aimed to accelerate RCNN. Apart from the complex training of RCNN, its inference involved a forward pass for each of the 2000…
Feature Extraction via Residual Networks
In the figure below we plot the evolution of depth in CNN architectures. Notice the big jump due to the introduction of the ResNet architecture.
Introduction to Convolutional Neural Networks

Introduction to Scene Understanding
In the previous chapters we have treated the perception subsystem mainly from starting the first principles that govern supervised learning to the deep learning…
Introduction to Transfer Learning
Transfer Learning is a foundational approach to learning.
Localization and Tracking
In the recursive state estimation section we have seen the formulation of the Bayes filter and its application in a simple problem of trying to maintain a latent (internal…
Mask R-CNN Semantic Segmentation
The semantic segmentation approach described in this section is Mask R-CNN based on this paper paper.
Mask R-CNN
is an extension of Faster R-CNN that adds a mask head to the…
Object Detection
In the introductory section, we have seen examples of what object detection is. In this section we will treat the detection
pipeline
itself, summarized below:
Object Detection & Semantic Segmentation Workshop
Object Detection and Semantic Segmentation Metrics
NOTE: The following example is based on here and its corresponding implementation
Recursive State Estimation
In the scene understanding chapter we started putting together the perception pipelines that resulted in us knowing where are the objects of interest in the image coordinate…
Region-CNN (RCNN) Object Detection
We can think about the detection problem as a classification problem of
all possible portions
(windows/masks) of the input image since an object can be located at any…
