Disclosed is a mechanical technology that kills parasitic pests, harmful bacteria and weed seeds in the soil by using high-temperature steam while moving forward by using a caterpillar with a self-powered device in order to smoothly perform the eco-friendly high-temperature steam soil disinfection in all types of soils, such as clays and sandy soils, having suitable moisture content; a mechanical technology in which the steam boiler is operated with power of an A/C generator to produce steam the steam is supplied to the re-heater installed on an upper portion of a nozzle through a high-pressure steam hose to increase the steam temperature to reheat the steam with high-temperature dry steam, thereby increasing the efficiency and effectiveness of high-temperature steam soil disinfection.

Provided is a fast mode-searching apparatus and method for motion-prediction. The fast mode-searching apparatus includes a probability information obtaining unit, a first inter mode searching unit, a second inter mode searching unit, and a selective intra mode searching unit. The probability information obtaining unit detects whether at least one of a macroblock of a previous frame, a macroblock of a current frame, and adjacent macroblocks corresponds to at least one of P16&#xd7;16, P16&#xd7;8, and P8&#xd7;16. The first inter mode searching unit performs an inter mode search on a block that is not detected by the probability information obtaining unit. The second inter mode searching unit determines whether the macroblock of the current frame corresponds to P16&#xd7;16 as a result of performing the inter mode search on a block detected by the probability information obtaining unit. The selective intra mode searching unit performs an intra mode search if the macroblock of the current frame corresponds to P16&#xd7;16.

A fast motion estimation apparatus and method in which motion estimation is carried out on a current block of a current frame of video image data with reference to a corresponding matching block of a previous frame are provided. The fast motion estimation apparatus includes: a determination unit which determines whether an SAD between pixel values of a current block of a current frame and a corresponding matching block of a previous frame is greater than a predefined threshold; an initial search unit which performs an initial search when the SAD is greater than the predetermined threshold to find which search point of a current search pattern is the minimal SAD point and to determine whether the minimal SAD point matches the center of the current search pattern; and a repetitive search unit which performs an iteration search when the minimal SAD point differs from the center of the current search pattern to reset the minimal SAD point to be a center of the current search pattern and to set a number of search points and the size of a search pattern based on from current search pattern to a center of the search window of the previous frame.
