MarkerEdgeColor — Specifies the color of the marker or the edge color for filled markers (circle, square, diamond, pentagram, hexagram, and the four triangles). MarkerFaceColor — Specifies the color of the face of filled markers. MarkerSize — Specifies the size of the marker in points (must be greater than 0).

Image analysis involves processing an image into fundamental components to extract meaningful information. Image analysis can include tasks such as finding shapes, detecting edges, removing noise, counting objects, and calculating statistics for texture analysis or image quality. Image analysis is a broad term that covers a range of techniques that generally fit into these subcategories.
You represent a truecolor image in MATLAB with a three-dimensional array of size M-by-N-by-3. Display functions in MATLAB and the Image Processing Toolbox treat such an array as a truecolor image. For example, let’s construct a truecolor image with two rows and two columns. The top two pixels should be red and blue, the bottom two, yellow and.

The contourf function uses the current colormap to fill the spaces between the levels in the plot. The first color fills the space between the lowest level and the level above it. The last color corresponds to Z-values that are greater than the highest level in the plot.If Z contains values that are smaller than the lowest level displayed in the plot, the region between the lowest level and.
Once the face image is detected the background is removed by using skin color detection in the face region. Yawning is detected by using a template matching technique with correlation coefficient. Then vector extracted from each of the above step is then linked together by using a vector classifier and classify the result as driver fit to drive or driver not fit to drive, if it is above the.
Specify the colors for a surface plot by including a fourth matrix input, C.The mesh plot uses Z for height and C for color. Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum.When you use a colormap, C is the same size as Z.Add a color bar to the graph to show how the data values in C correspond to the colors in the colormap, and set the view of.
