In the first part an algebraic error analysis for the calculated surface Gaussian and mean curvatures of 3-D range images is presented. The error analysis results are used to illustrate the effect of noise on the segmentation of range images using the curvature 8-sign label scheme. In the second part a segmentation procedure for 3-D range images based on conclusions deducted from the first part is proposed. In this procedure, jump edges are first obtained. Then a curvature 3-sign label scheme is used for the segmentation. A simple method is used to check the boundary points between segmentation patches. If a boundary point lies on a planar region it is deleted. In the planarity test we use some of the intermediate results from the first part of the paper. Experimental results and comments are given.

Error Analysis My algebra 2 students needed more practice solving equations with rational exponents. I was trying to think of an interesting and yet still effective way for them to keep practicing, and then I thought about how the errors they make tend to be the same again and again. That reminded me that I hadn't done an error analysis activity in a long time - and just like that, the lesson was created. I assigned each table pair one problem, where they had to find the mistake, explain it, and do the work correctly. Then each pair was called to present their findings to the class; the class then worked out the problem http://www.sciencedirect.com/science/article/pii/0031320390901288 and if they all agreed that they had found the correct solution, I allowed them to move on.Students were generally good at finding the mistakes I had made. Will this activity help keep them from making the same mistakes in the future? We'll find out next week.Here are the twelve problems plus homework.

I'm a first-year math teacher in Seattle - I love http://exponentialcurve.blogspot.com/2009/09/algebra-2-error-analysis.html this idea of error analysis! Will definitely use it - thanks! 5:43 PM Dan Greene said... Hi Linda, I hope it helps! Good luck with the whole first-year-teacher thing. :) 11:22 PM Kala_P said... i might've missed your update on this but did it end up helping your students find their errors better and make those errors less? i'm considering trying this next week. thanks! 1:57 PM Post a Comment Newer Post Older Post Home Subscribe to: Post Comments (Atom) About Me Dan Wekselgreene I am a math teacher in the Bay Area, California. Previously, I taught for eleven years at Downtown College Prep charter high school in San Jose, where the target student is low-skilled and of the first generation to go to college. Currently, I am teaching at Capuchino high school in San Bruno. On this blog, I will post strategies that I am trying, and I would love to see strategies that others are using to help bring students up to grade level and teach them real math skills.
