Due to the imperfections of the imaging system, the transmission medium, and the recording device, the digital images are often contaminated by various noises during the formation, transmission, and recording processes thereof. In addition, noise may also be introduced into the resulting image at some point in the image processing when the input image object is not as expected. These noises often appear as an isolated pixel or block of pixels on the image that causes a strong visual effect. In general, the noise signal is not correlated with the object to be studied-it appears in the form of useless information, disturbing the observable information of the image. For digital image signals, the noise table is more or less extreme values, and the extreme values act on the real gray values of image pixels through addition and subtraction to cause bright and dark point interference on the image, so that the image quality is greatly reduced, and the follow-up work of image restoration, segmentation, feature extraction, image identification and the like is influenced. Two basic issues must be considered to construct an effective noise suppression filter: the noise in the target and the background can be effectively removed; meanwhile, the shape, the size and the specific geometric and topological structure characteristics of the image target can be well protected.
One of the commonly used image filtering modes is a non-linear filter, generally speaking, when the signal spectrum and the noise spectrum are mixed or when the signal contains non-superimposed noise, such as noise caused by system nonlinearity or the presence of non-gaussian noise, etc.), the conventional linear filtering techniques, such as fourier transform, while filtering out noise, always blur the image details (such as edges, etc.) in some way, thereby causing the positioning accuracy of the image linear features and the extractability of the features to be reduced. The nonlinear filter is based on a nonlinear mapping relation of an input signal, a specific noise can be mapped to be zero approximately, the main characteristic of the signal is reserved, and therefore the nonlinear filter can overcome the defects of the linear filter to a certain extent.
By adopting the brushing time setting platform, aiming at the technical problem that the rechargeable toothbrush in the prior art cannot effectively control the brushing time of users at different ages, the contrast resolution operation is carried out on the nonlinear interpolation image, wherein the resolution of the contrast is carried out on each Y component value of each pixel point based on the nonlinear interpolation image; under the condition that the contrast ratio does not meet the requirement, adopting curve pull-up equipment to execute image brightness curve pull-up processing so as to obtain a curve pull-up image with the contrast ratio reaching the standard; on the basis of customized image recognition, the time required by one-time tooth brushing is automatically set based on the recognition result of the age group of the user, so that the tooth brushing habit of the user is developed while the electric power is saved, and the tooth brushing effect is ensured.
