In checking harvesting discipline and quality control for oil palm fruits, color has presumably been an important guide to whether the oil content has reached a maximum where the fruit bunch is ready for cutting. However, establishing a single and harmonious standard base on color is a very contentious issue in the oil palm industry because of the subjective nature of the human vision of color. This was further complicated due to the lack of information on fruit color upon which to base a definite ripeness criterion. We demonstrated in this paper that this problem can be solved using machine vision technology. Methods used were to treat color in HSI (Hue, Saturation and Intensity) color space and applied multivariate discriminant analysis. These have proven to be highly effective for color evaluation and image processing. The vision system was trained to classify oil palms into four quality grades according to PORIM (Palm Oil Research Institute of Malaysia) inspection standards. These are the unripe, the underripe, the optimally ripe and the overripe classes. Depending upon the quality feature evaluated, misclassification by the vision system varied from 5 to 12% but averaged at about 8%. Machine vision disagreement ranged from 2 to 19%.

With the success of Uni-Speech chip [1] designed for advance Speech recognition system, there is an effort to develop a cost efficient version of the Uni-Speech chip targeted for mass consumer market speech-recognition related applications with special focus in improving power consumption. In this paper, a new low cost speech device called UniSpeech-Lite is described. The UniSpeech-Lite is an integrated SoC (System on Chip), containing the speech functions for prompt, record, speaker-independent voice recognition, suitable for many applications such as portable speech related educational devices, toys, digital recorder, voice based remote control, etc. UniSpeech-Lite is specifically targeted for stable performance, low cost and low power-consumption. This chip will enable extensive deployment of applied speech technology in many fields and achieve favorable economic and social benefits.
