#### The Application of Linear Systems Analysis to Image Processing. Some Notes.

(MIT Artificial Intelligence Laboratory, 1974)

The Fourier transform is a convenient tool for analyzing the performance of an image-forming system, but must be treated with caution. One of its major uses is turning convolutions into products. It is also used to transform ...

#### Vision Review

(MIT Artificial Intelligence Laboratory, 1978-05)

#### LANDSAT MSS Coordinate Transformations

(1978-02-01)

A number of image analysis tasks require the registration of a surface model with an image. In the case of satellite images, the surface model may be a map or digital terrain model in the form of surface elevations on ...

#### Dynamics of a Three Degree of Freedom Kinematic Chain

(1977-10-01)

In order to be able to design a control system for high-speed control of mechanical manipulators, it is necessary to understand properly their dynamics. Here we present an analysis of a detailed model of a three-link ...

#### Picking Parts out of a Bin

(1983-10-01)

One of the remaining obstacles to the widespread application of industrial robots is their inability to deal with parts that are not precisely positioned. In the case of manual assembly, components are often presented ...

#### Fan-beam Reconstruction Methods

(1977-11-01)

In a previous paper a technique was developed for finding reconstruction algorithms for arbitrary ray-sampling schemes. The resulting algorithms use a general linear operator, the kernel of which depends on the details ...

#### Extended Gaussian Images

(1983-07-01)

This is a primer on extended Gaussian Images. Extended Gaussian Images are useful for representing the shapes of surfaces. They can be computed easily from: 1. Needle maps obtained using photometric stereo, or 2. Depth ...

#### Looking in the Shadows

(MIT Artificial Intelligence Laboratory, 1976-05)

The registration of an image with a model of the surface being imaged is an important prerequisite to many image understanding tasks. Once registration is achieved, new image analysis techniques can be explored. One approach ...

#### Density Reconstruction Using Arbitrary Ray Sampling Schemes

(1977-09-01)

Methods for calculating the distribution of absorption densities in a cross section through an object from density integrals along rays in the plane of the cross section are well known, but are restricted to particular ...

#### The Variational Approach to Shape from Shading

(1985-03-01)

We develop a systematic approach to the discovery of parallel iterative schemes for solving the shape-from-shading problem on a grid. A standard procedure for finding such schemes is outlines, and subsequently used ...
