Framework.Its all calculating uses floating-point arithmetic, and there are no positions or integer arithmetic to instruct this moment.Further, since GPU is aimed at
Image procossing design, therefore storage system is actually a two-dimensional fragmented storage space, including a segment number (is therefrom read
Take image) and two-dimensional address (X, Y coordinates in image).In addition, without any indirect write command.Write address output is by grating
It manages device to determine, and cannot be by routine change.This is greatly to challenge for the algorithm among memory for NATURAL DISTRIBUTION.
Last point does not allow to communicate between the treatment process of different fragments.In fact, fragment processor is that a SIMD data parallel is held
Row unit independently executes code in all fragments.
In spite of above-mentioned constraint, but GPU still can efficiently perform a variety of operations, from linear algebra and signal processing

Good starting point.Brook is the extension of C language, incorporates the simple data multiple programming construction that can map directly to GPU.
The data for storing and operating through GPU are visually likened into " stream " (stream), similar to the array in standard C.Core
It (Kernel) is the function operated on stream.A core function is called to mean on a series of inlet flows real on stream element
Implicit circulation has been applied, i.e., core body has been called to each stream element.Brook additionally provides reduction mechanism, such as flows to one
In all element carry out and maximum value or product calculate.Brook also conceals all details of figure API, and handle completely
The similar two dimensional memory system unfamiliar parts of user many in this way have carried out virtualization process in GPU.It is write with Brook
Application program includes linear algebra subprogram, fast Fourier transform, ray tracing and image procossing.Utilize the X800XT of ATI
With the GeForce 6800Ultra type GPU of Nvidia, condition is executed in identical cache, SSE assembly code optimizing Pentium 4
Under, the speed of many such applications lifts up to as many as 7 times.
Using thermostatic control type hair dryer of the invention, for the skill of hair dryer security protection scarce capacity in the prior art
Art problem, for, there are when plastic target, to prevent plastic target by roastingization, carrying out corresponding target in hair dryer closer distance
Alarm operation, wherein for the distribution situation of marginal point in image, the different zones of image are carried out with the contrast of different amplitudes
It is promoted, to facilitate subsequent various image procossings；Using twin-stage filter patterns and self-adaption binaryzation adjusting thresholds mode,
Improve the effect of image preprocessing；Use real time correction equipment with the direction vector based on the gun type camera to the rifle

Second pixel processing equipment is connect with the first pixel processing equipment, for obtain multiple reference image vegetarian refreshments and
The corresponding multiple target pixel points of multiple reference image vegetarian refreshments, determine each reference coordinate to its corresponding coordinates of targets
Horizontal displacement averages to obtain image level amount of movement to each horizontal displacement of each reference coordinate, determines each ginseng
The vertical displacement of coordinate to its corresponding coordinates of targets is examined, averages each vertical displacement of each reference coordinate to obtain figure
As vertical movement, the timestamp of timestamp and the follow-up time based on the present image determines time amount of movement, with
And the gun type camera is calculated based on the time amount of movement, the described image amount of moving horizontally and described image vertical movement
Direction vector.
7. thermostatic control type hair dryer as claimed in claim 6, which is characterized in that the hair dryer further include:
Real time correction equipment is connect, for receiving respectively with the gun type camera and the second pixel processing equipment
The direction vector of gun type camera is stated, and the direction vector based on the gun type camera carries out vector to the gun type camera
Correction.
8. thermostatic control type hair dryer as claimed in claim 7, it is characterised in that:
In the intelligent piecemeal equipment, the fog-level of the Wiener Filtering is smaller, to the Wiener Filtering into
The quantity for the image block that the processing of row piecemeal obtains is more.
9. thermostatic control type hair dryer as claimed in claim 8, it is characterised in that:
The amplitude for promoting processing to the contrast that each region to be reinforced executes is both greater than the same amplitude.
10. thermostatic control type hair dryer as claimed in claim 9, it is characterised in that:
The sum that the pixel analytical equipment is also used to work as pixel occupied by plastic target subgraph is less than described default
When pixel quantity, issues and plastic target signal is not present.
