In addition, image filtering, namely suppress the noise of target image under the condition as far as possible retaining image detail feature, be indispensable operation in Image semantic classification, the quality of its treatment effect will directly have influence on the validity and reliability of successive image process and analysis.Due to the imperfection of imaging system, transmission medium and recording unit etc., digital picture is often subject to the pollution of multiple noise in its formation, transmission log process.In addition, also not as during anticipation also can in result images noise be introduced when what input as object in some link of image procossing.These noises often show as isolated pixel point or the pixel block that causes stronger visual effect on image.Usually, noise signal is uncorrelated with the object that will study, and he occurs with useless message form, upsets the observable information of image.For data image signal, psophometer is either large or small extreme value, these extreme values act on the true gray-scale value of image pixel by plus-minus, bright, dim spot interference is caused at image, greatly reduce picture quality, affect the carrying out of the follow-up work such as image restoration, segmentation, feature extraction, figure identification.The filtering machine constructing a kind of effective restraint speckle must consider that two basic problems can remove the noise in target and background effectively; Meanwhile, the shape of image object, size and specific geometry and topological features can be protected well.Main image filter comprises linear filter, nonlinear filter, median filter and Morphologic filters etc.
In general, when signal spectrum and noise spectrum aliasing or when containing nonadditivity noise in signal, as the noise that caused by mission nonlinear or there is non-Gaussian noise etc., traditional linear filter technology, as Fourier conversion, while filtering noise, federation's blurred picture details (as edge etc.) in some way, and then cause reducing as the positioning precision of linear feature and the extraction property of feature.And nonlinear filter is based on a kind of Nonlinear Mapping relation to input signal, often a certain specific noise can be mapped as zero approx and stick signal want feature, thus it can overcome the weak point of linear filter to a certain extent.
In addition, timer is one of fundamental of normally running of communication protocol, is mainly used in the task that various timing and frame retransmit.Communication protocol realizes used timer in Single Chip Microcomputer (SCM) system, and timing accuracy is less demanding, but quantitative requirement is larger.Because hardware resource is limited, can not be each independent task matching hardware timer, the method for multiple software timer can only be simulated by single hardware timer, meet the timing application needs in agreement.The appearance of timer, has made the work in the quite a lot of people's of needs control time become simply many.
