The invention discloses a fresh meat freshness detection method and system, and relates to the technical field of food quality safety detection. The method comprises the following steps: acquiring fresh meat multi-index colorimetric array image data, and constructing an improved YOLOv11n model for analysis; according to the model, an original Bottleneck convolution module is replaced by a NewBlock module, the NewBlock module comprises three branches which are connected in parallel, the first branch adopts grouping convolution to extract global initial features, the second branch captures color texture details through cascade multi-scale convolution, the third branch carries out convolution on part of channels, and the rest channels are directly transmitted to extract key features; and after the output of each branch is integrated by the feature fusion layer, the detection layer realizes automatic grading of the freshness of the fresh meat. According to the method, full-coverage perception and high-precision real-time automatic detection of the corruption features are realized, and the problems that a traditional method is high in subjectivity and long in period and depends on professional equipment are effectively solved.

The invention discloses a three-dimensional grid vertex coloring method, device and equipment based on an implicit representation and separated reflection color network. The method comprises the steps of collecting a multi-view data set of an object to be colored, estimating a camera pose through a multi-level view structure recovery method, and determining a standard sampling cubic domain and a grid file; training a NeuS framework to obtain a model containing a geometric branch network and a separated reflection color network; grid vertex coordinates and triangular surface indexes are extracted through a geometric branch network, a color network processes the vertex coordinates to obtain an RGB vertex set, and after gravity center interpolation smooth coloring is conducted, a color three-dimensional grid with explicit vertex colors is generated and written into a file; coloring is completed based on the file. According to the method, UV expansion and illumination modeling are not needed, accurate coloring is achieved through the separated color network, the color grid rendering efficiency is high, compatibility is high, and the problems of texture dislocation and the like can be effectively avoided.

System comprising: a memory that stores: an indexed color history with an entry that stores a color value of a previously encoded pixel; an encoding logic that communicates with the memory and is configured to: encode a current pixel as an index value that references the entry in the indexed color history if a color value of the current pixel is within a difference threshold based on the color value of the previously encoded pixel; otherwise, encode the current pixel as an uncompressed color or pixel value or by inserting it into the indexed color history.
