Detailed Description
Embodiments of the electronic device content driven platform of the present invention will be described in detail below with reference to the accompanying drawings.
A projector, also called a projector, is a device that can project images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV, etc. through different interfaces to play corresponding video signals.
Projectors are widely used in homes, offices, schools and entertainment places at present, and have different types such as CRT, LCD and DLP according to different working modes.
Light sources used for projectors include conventional high-intensity gas discharge light sources (e.g., ultra-high pressure mercury lamps, short arc xenon lamps, metal halide lamps) and novel light sources typified by LED light sources and laser light sources. The conventional light source projector generally makes the projected image darken and turn yellow (such as brightness attenuation, color saturation contrast reduction and the like) along with the attenuation of the emergent light of the light source after being used for a period of time, and in a use occasion with higher requirements on image quality, even if the bulb still emits light, the bulb has to be replaced accordingly. The light attenuation is a major obstacle that cannot be overcome by the conventional light source. With the development of semiconductor lighting technology and laser technology, LED light sources and laser light sources have been rapidly developed in the lighting field and widely applied in the display field. The LED is the earliest product used for the projector in a novel light source, and because the LED can enable the imaging structure of the projector to be simpler, the projector product which is smaller in size, easy to carry and simple to use brings great convenience to teaching, business and personal entertainment. Meanwhile, the laser is used as a brand new projection light source, the defects of a projector using the traditional light source in the aspects of brightness attenuation, color, power consumption and the like are overcome, and the laser has the characteristic of being on and on as the laser belongs to a cold light source, so that the phenomena of waiting for starting and stable light emission of the traditional light source are fundamentally eliminated.

In addition, image filtering, namely, suppressing the noise of the target image under the condition of keeping the detail features of the image as much as possible, is an indispensable operation in image preprocessing, and the effectiveness and reliability of subsequent image processing and analysis are directly affected by the quality of the processing effect.
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 method can effectively remove the noise in the target and the background, and can well protect the shape, the size and the specific geometric and topological structure characteristics of the image target.
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.
