The present application provides a kind of sparse gradient enhanced edge preserving image smoothing method, comprising: introducing structure fidelity term on the basis of existing global optimization model containing data fidelity term, in structure fidelity term, the gradient of input image is preprocessed using the way of combining mapping function and bilateral filtering;And introduce sparse gradient enhancement term on the basis of structure fidelity term, in sparse gradient enhancement term, L2 norm and L1 norm are used to constrain the gradient of output image to enhance sparsity, L1 norm is iteratively solved by combining subgradient method, fast Fourier transform and alternating direction multiplier method, or L p norm is used to constrain the gradient of output image, and L p Norm is converted to L1 norm for solving by iterative reweighting method, and preconditioned conjugate gradient method is used to improve calculation efficiency in solving process.The present application can retain complete semantic information while showing sparse smoothing effect when processing simple and complex non-texture images and texture images.

The invention relates to the technical field of tassel cloth conveying and dust removal, in particular to a garment production and processing conveying device convenient for dust removal, which comprises a conveying table, two fixed seats are fixedly mounted on the upper surface of the conveying table close to two sides respectively, and five fixed frames and a movable frame are mounted on the upper surfaces of the two fixed seats respectively; an adjusting mechanism is arranged on the inner sides of the five fixed frames and the movable frame, and a rotary throwing mechanism and a turning and pressing dust collection smoothing mechanism are sequentially arranged at the movable end of the adjusting mechanism. The rotary throwing mechanism can effectively throw cotton fibers attached to tassels on tassel cloth towards the irregular dust collection box, and the damage of wiredrawing or edge falling possibly caused by bristle cleaning to the tassels is avoided; the turning and pressing dust collection smoothing mechanism arranged in the device can effectively perform rapid dust collection operation on cotton fibers thrown in the front, and meanwhile rubber carding teeth can effectively smooth tassels scattered and separated due to dust removal operation on tassel cloth.
