此匯編程序實現A/D轉換功能,應用于pic單片機上,A/D采用中斷方式。該程序通過單片機的RA2模擬通道送入一直流電壓,當送入的直流電壓大于2.5V時,8個LED閃動,當直流電壓恢復到2.5V以下時,LED停止閃動。為了防止干擾,本程序對直流電壓采樣10次后再作判斷,中間的采樣結 果用間接尋址的方式存取。

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.

SCSI Multimedia Commands 鈥?3 (MMC-3) T10/1363-D 5.16 READ CAPACITY Command The READ CAPACITY command (Table 144) provides a means for the Initiator to request information regarding the capacity of the Logical Unit. This command shall not report the correct capacity of the recorded data for CD-R, CD-RW and DVD-R/-RW media that does not have a Lead-out in the last Session or last Border-out. For CD-ROM, the returned logical block address is modified to allow returning a possibly inexact value (but one with a known error bound) based on the Table of Contents data
