The law's nickname is a reference to the line Go ahead, make my day uttered by actor Clint Eastwood 's character Dirty Harry Callahan (in the 1983 police film Sudden Impact). Justifiable homicide inside one's home is distinct, as a matter of law, from castle doctrine's no duty to retreat therefrom.
Optical character recognition (also optical character reader, OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text ...
Most OCR systems use a combination of hardware (specialized circuit boards) and software to recognize characters, although some inexpensive systems do it entirely through software. Advanced OCR systems can read text in large variety of fonts, but they still have difficulty with handwritten text. The potential of OCR systems is enormous because they enable users to harness the power of computers to access printed documents. OCR is already being used widely in the legal profession, where searches that once required hours or days can now be accomplished in a few seconds.
