#### Histogram of an Image

lesson

There is a lot of information in an image which we need to summarize somehow. An intensity histogram is one form of summary that provides useful information about how well the exposure of our camera is adjusted.

lesson

We learn how to describe the 3D pose of an object by a 4×4 homogeneous transformation matrix which has a special structure.

lesson

We learn how to describe the orientation of an object by a 3×3 rotation matrix which has some special properties.

lesson

We learn how to describe the 2D pose of an object by a 3×3 homogeneous transformation matrix which has a special structure. Try your hand at some online MATLAB problems. You’ll need to watch all the 2D “Spatial Maths” lessons to complete the problem set.

We revisit the fundamentals of 3D geometry that you would have learned at school: coordinate frames, points and vectors.

lesson

One very powerful trick used by humans is binocular vision. The images from each eye are quite similar, but there is a small horizontal shift, a disparity, between them and that shift is a function of the object distance.

lesson

For a binary image that contains multiple blobs we must first transform it using connectivity analysis or region labeling. Then we can describe each of the blobs in the scene we first need to transform the image using connectivity analysis. Each of the blobs can then be described in terms of its area, centroid position, […]

Humans have long been fascinated with seeing images and movies in ā3Dā. Let’s look at how human stereo vision works and some of the technologies used to present images to our eyes in ā3Dā.

lesson

Let’s recap the important points from the topics we have covered about human depth perception, display of 3D images and estimating 3D scene structure using stereo and other types of sensors.
