The field of Affective Computing AC expects to narrow the communicative gap between the highly emotional human and the emotionally challenged computer by developing computational systems that recognize and respond to the affective states of the user.
Thresholding[ edit ] The simplest method of image segmentation is called the thresholding method. This method is based on a clip-level or a threshold value to turn a gray-scale image into a binary image.
There is also a balanced histogram thresholding. The key of this method is to select the threshold value or values when multiple-levels are selected. Several popular methods are used in industry including the maximum entropy method, Otsu's method maximum varianceand k-means clustering.
Recently, methods have been developed for thresholding computed tomography CT images. The key idea is that, unlike Otsu's method, the thresholds are derived from the radiographs instead of the reconstructed image.
In these works decision over each pixel's membership to a segment is based on multi-dimensional rules derived from fuzzy logic and evolutionary algorithms based on image lighting environment and application.
Data clustering Source image. Note that a common technique to improve performance for large images is to downsample the image, compute the clusters, and then reassign the values to the larger image if necessary.
The K-means algorithm is an iterative technique that is used to partition an image into K clusters. The difference is typically based on pixel colorintensitytextureand location, or a weighted combination of these factors. K can be selected manually, randomlyor by a heuristic.
This algorithm is guaranteed to converge, but it may not return the optimal solution. The quality of the solution depends on the initial set of clusters and the value of K.
The idea is simple: Assuming the object of interest is moving, the difference will be exactly that object. Improving on this idea, Kenney et al.
They use a robot to poke objects in order to generate the motion signal necessary for motion-based segmentation. Interactive segmentation follows the interactive perception framework proposed by Dov Katz  and Oliver Brock . Compression-based methods[ edit ] Compression based methods postulate that the optimal segmentation is the one that minimizes, over all possible segmentations, the coding length of the data.
The method describes each segment by its texture and boundary shape. Each of these components is modeled by a probability distribution function and its coding length is computed as follows: The boundary encoding leverages the fact that regions in natural images tend to have a smooth contour.
This prior is used by Huffman coding to encode the difference chain code of the contours in an image.List of best Matlab Project Topics for your Final Year Project from a list of + Matlab Projects in various Domains such as Image Processing, Robotics, Power Systems etc covering all branches of Engineering such as Civil, Biomedical, Electronics, Electrical, Mechanical and Aeronautical.

Within the M.A. in Social Science, students may apply directly to the concentration in Demographic and Social Analysis. T his is a short tutorial that documents how to make a MATLAB plot on top of an image background. This can be useful for a variety of things but when I first learned about it, I was a bit confused by how the axes seem to be flipped sometimes when you do this.
