与“皮肤年龄”相关的皮下成分的纹理结构使我们能够识别和分析其独特的特征，从而在建立准确的皮肤年龄模型方面取得实质性进展。首先通过使用激光散斑成像的纹理分析的应用，其对λ= 650 nm光谱带区域内的纹理效应敏感。在第二阶段，使用贝叶斯推理方法来选择属性，并从中构建预测模型。ResultsThis技术使我们能够对比不同的皮肤年龄模型，例如激光散斑效应与更广泛使用的正常光（LED）成像方法，从而表明我们的基于激光散斑的技术产生更好的结果。成本低且能够在真实的时间内操作;具有与用于皮肤年龄识别目的的高成本仪器（例如共聚焦显微镜或类似成像装置）竞争的潜力。
ObjectiveThe textural structure of ‘skin age’‐related subskin components enables us to identify and analyse their unique characteristics, thus making substantial progress towards establishing an accurate skin age model.MethodsThis is achieved by a two‐stage process. First by the application of textural analysis using laser speckle imaging, which is sensitive to textural effects within theλ= 650 nm spectral band region. In the second stage, a Bayesian inference method is used to select attributes from which a predictive model is built.ResultsThis technique enables us to contrast different skin age models, such as the laser speckle effect against the more widely used normal light (LED) imaging method, whereby it is shown that our laser speckle‐based technique yields better results.ConclusionThe method introduced here is non‐invasive, low cost and capable of operating in real time; having the potential to compete against high‐cost instrumentation such as confocal microscopy or similar imaging devices used for skin age identification purposes.
