 The questions below are meant to highlight key aspects or principles related to the reading.  Being able to answer them prior to the lectures of that week should provide you with some nominal uderstanding of what will be covered so that you may focus on understanding the material and listening, as opposed to the written material on the board.  Some of the questions may be slight variations on each other. Many involve answering multiple questions, so maybe we should think of each question more as a //question set//, where sometime the set consists of an individual element.

 In my notes, I use the symbol M, however Szeleski (Sec 2.1.5) and the DLT reading use the symbol P to denote the camera (projection) matrix.
