Area analysis of thermal images can detect delayed healing in diabetes foot ulcers, but not venous leg ulcers (VLU) assessed in the home environment. This study proposes using textural analysis of thermal images to predict the healing trajectory of venous leg ulcers assessed in home settings. Participants with VLU were followed over twelve weeks. Digital images, thermal images and planimetry of wound tracings of the ulcers of 60 older participants was recorded in their homes by nurses. Participants were labelled as healed or unhealed based on status of the wound at the 12th week follow up. The weekly change in textural features was computed and the first two principal components were obtained. 60 participants (aged 80.53 ± 11.94 years) with 72 wounds (mean area 21.32 ± 51.28cm²) were included in the study. The first PCA of the change in textural features in week 2 with respect to week 0 were statistically significant for differentiating between healed and unhealed cases. Textural analysis of thermal images is an effective method to predict in week 2 which venous leg ulcers will not heal by week 12 among older people whose wounds are being managed in their homes.

热图像的区域分析可以检测糖尿病足溃疡的延迟愈合，但不能检测家庭环境中评估的静脉腿部溃疡 (VLU)。这项研究建议使用热图像的纹理分析来预测在家中评估的腿部静脉溃疡的愈合轨迹。对患有 VLU 的参与者进行了十二周以上的随访。护士在家中记录了 60 名老年参与者溃疡伤口的数字图像、热图像和面积测量。根据第 12 周随访时伤口的状态，参与者被标记为愈合或未愈合。计算纹理特征的每周变化并获得前两个主成分。该研究包括60 名参与者（年龄 80.53 ± 11.94 岁），有 72 个伤口（平均面积 21.32 ± 51.28cm ^{2 ）。}第 2 周相对于第 0 周的纹理特征变化的第一个 PCA 对于区分愈合和未愈合的病例具有统计学意义。热图像的纹理分析是一种有效的方法，可以在第 2 周预测在家中处理伤口的老年人中哪些腿部静脉溃疡在第 12 周时不会愈合。
