An adjustable garment includes an article of clothing and a plurality of unique adjustment features. The oxidation is performed at a temperature and for a time duration such that the formation of the oxide layer causes the injection of a controlled number of atoms of the substrate from a region proximate to an interface between the newly formed oxide layer and the substrate into the upper regions of the substrate to reduce strain. Based on a result of the image data analysis, an event detection unit determines to make identifiable to a client a human figure that should be monitored by the client and to apply masking to a human figure that should not be monitored by the client to make it unidentifiable to the client. The novel method of the present invention may include novel steps for selecting motion vectors, block modes, and for applying a complexity-control algorithm to encode the received input video data sequence in accordance with the identified target complexity level.
