  • Recovering 3-D structure from motion in noisy 2-D images is a problem addressed by many vision syste

    Recovering 3-D structure from motion in noisy 2-D images is a problem addressed by many vision system researchers. By consistently tracking feature points of interest across multiple images using a methodology first described by Lucas-Kanade, a 3-D shape of the scene can be reconstructed using these features points using the factorization method developed by Tomasi-Kanade.

  • DAC技术用语 (D/A Converters Defini

    Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codechange exhibits 1⁄2 LSB differential non-linearity. Differentialnon-linearity may be expressed in fractional bits or as a percentageof full scale. A differential non-linearity greater than1 LSB will lead to a non-monotonic transfer function in aDAC.Gain Error (Full Scale Error): The difference between theoutput voltage (or current) with full scale input code and theideal voltage (or current) that should exist with a full scale inputcode.Gain Temperature Coefficient (Full Scale TemperatureCoefficient): Change in gain error divided by change in temperature.Usually expressed in parts per million per degreeCelsius (ppm/°C).Integral Nonlinearity (Linearity Error): Worst case deviationfrom the line between the endpoints (zero and full scale).Can be expressed as a percentage of full scale or in fractionof an LSB.LSB (Lease-Significant Bit): In a binary coded system thisis the bit that carries the smallest value or weight. Its value isthe full scale voltage (or current) divided by 2n, where n is theresolution of the converter.Monotonicity: A monotonic function has a slope whose signdoes not change. A monotonic DAC has an output thatchanges in the same direction (or remains constant) for eachincrease in the input code. the converse is true for decreasing codes.

    This example implements a gameport translator on the PIC16C765. The firmware translates a gaming device plugged into the gameport to a USB gaming device. The firmware is set up to translate the DexxaTM eight-button gamepad. Changes to the firmware will be necessary for a different gaming device.

    SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating with a 100MHz Bus Clock. The rating is based on Dhrystone 2.1. It shows the rate when I+D Caches are disabled or enabled, with or without MMU and I Cache is disable or enabled, with or without MMU.

  • CFlowchartEditor is an extension of CDiagramEditor. CDiagramEditor is a vector editor, with a CWnd-d

    CFlowchartEditor is an extension of CDiagramEditor. CDiagramEditor is a vector editor, with a CWnd-derived window (CDiagramEditor), a data container (CDiagramEntityContainer) holding the draw-objects, undo stack and managing copy and paste, and objects derived from CDiagramEntity representing objects drawn on screen. CDiagramEditor lacks one feature (that is difficult to implement in both simple and general fashion) - links. Manually maintaining links in a - for example - flowchart or network topography map is unwieldy. Therefore, I ve created a reference implementation for one way of adding this functionality.
