The present invention discloses an intelligent induction miner's lamp. A heat dissipating portion in the miner's lamp includes a substrate, a reflector, and heat sinks; the substrate provided with a first through-hole in the center thereof is arranged on an inner wall of the reflector; an upper surface of the substrate is provided with a plurality of the heat sinks; the substrate, the reflector, and the heat sinks are integrated during casting; the power source cover is provided with a latching switch and is arranged on the reflector; the reflector is provided with a lens whose center is a recessed blind via; the lens is located on a side of a lower surface of the substrate, a ring protrusion is provided around the recessed blind via, and a sensor is arranged in the recessed blind via; the lens, the reflector, and the power source cover form a cavity; a driving power source fixed to the substrate is arranged in the cavity; and the lower surface of the substrate is provided with a light emitting element corresponding to the ring protrusion. In the present invention, the latching switch is arranged on the power source cover. Before the miner's lamp is mounted, whether the miner's lamp has a sensing function can be controlled by using the latching switch. In this way, use of other lamps of the same type is not affected, the costs are low, and mounting, cable layout, and subsequent maintenance are easy.

An image processor generates a Super-Resolution (SR) frame by upscaling. A Human Visual Preference Model (HVPM) helps detect random texture regions, where visual artifacts and errors are tolerated to allow for more image details, and immaculate regions having flat areas, corners, or regular structures, where details may be sacrificed to prevent annoying visual artifacts that seem to stand out more. A regularity or isotropic measurement is generated for each input pixel. More regular and less anisotropic regions are mapped as immaculate regions. Higher weights for blurring, smoothing, or blending from a single frame source are assigned for immaculate regions to reduce the likelihood of generated artifacts. In the random texture regions, multiple frames are used as sources for blending, and sharpening is increased to enhance details, but more artifacts are likely. These artifacts are more easily tolerated by humans in the random texture regions than in the regular-structure immaculate regions.

A frame-rate converter reduces halo artifacts along edges of moving objects. Halo artifacts occur on interpolated frames where a moving object covers and uncovers pixels along its edges. Motion estimation among three original frames produces hybrid direction motion vectors that are bi-directional for background and objects, but are unidirectional for covered and uncovered regions, since motion vectors with large matching errors are deleted. Covered regions in the interpolated frame are detected as intersecting only a forward but no backward hybrid motion vector. Bi-directional motion estimation from the hybrid motion vectors of two original frames produces refined motion vectors for the interpolated frame. Refined motion vectors in the covered regions are deleted and replaced with hybrid motion vectors from the original frames. Hybrid motion vectors from the original frames are assigned to the critical covered regions rather than using interpolated vectors in the covered regions, reducing halo artifacts.
