A system for sorting and classifying users of an image information management system is disclosed. The system for sorting and classifying users of an image information management system according to the present invention comprises some identical sub-systems, and every two sub-systems are interconnected. The sub-system comprises a user information encoding module, a user information decoding and authority identifying module, a user sorting module, a user classifying module, a command performing module, an authorized user collection database and a resource information database. The resource information database comprises real-time images, history images and control right commands of cradle heads and lens of cameras. The present invention resolves the problem of ordered accessing and utilizing of image information in a super-large-scale advanced real-time monitoring information management system, and realizes the object that local failures do not affect the normal work of the other parts by connecting every two sub-systems to each other and arranging the user identification entrance in each one of sub-systems.

A probe assembly used in testing instrument for determining optical signal within a test cell, comprising a top plate () with a through-hole () therein; a cylindrical light hood () having a central channel (); the lower end of the optical pickup () is inserted into said channel () and surrounded by said light hood, and said light hood can slide down and up within a small distance isolating said one test cell of the sample being detected from its adjacent cells and surroundings when the lower end of said light hood is in said protruding position, so that the light interference from the adjacent test cells and surroundings with (to) the determination of the sampling being detected can be avoided. Also, the present invention further relates to the light hood included in the probe assembly and the instruments including the probe assembly.

A VLSI wavelet transform (WT) architecture suitable for use in a discrete wavelet transform (DWT) or a discrete wavelet packet transform (DWPT). The WT architecture has a multiplier; an accumulator; at least two address generators that has a first address generator and a second address generator; a control unit; a memory of result that stores computation results; and a memory of table, which pre-stores all possible weights, each of which weights is a product of some specified filter coefficients for performing a DWT/DWPT with parameters of decomposition level, length of data segment, and filter length. The first address generator and the control unit receive data input, the control unit exports control signals to multiplier, accumulator, second address generator, and memory of table. The memory of the table also receives outputs from the first address generator and the second address generator to select the desired weights of the filter coefficients, which are sent to the multiplier to obtain a product with the data input. The product is sent to the accumulator to add into a corresponding sum, and the memory of result receives the corresponding sum and an address output of the second address generator to address the received corresponding sum, in which when all of the data input in the DWT/DWPT are completely inputted, each the corresponding sum is an end result of the DWT/DWPT.

Architecture of discrete wavelet transformation

A method of signal compression. An input signal is divided into a plurality of segments. Each of the segments is decomposed by wavelet packet transform to a plurality of levels, so that each of the segments is in a form of a group of coefficients in each of a plurality of domains corresponding to each of the levels. Each of the domains is divided into a plurality of sub-domains to calculate a degree of characteristic concentration corresponding thereto. One of the domains having a highest degree of characteristic concentration is select to perform bit allocation and quantization, so that the group of coefficients in the selected domain is represented as an information. The information is formatted into a frame for transmission, and then the frame is output.
